| Annotation: | The main aim of our common project is study superconductivity in nitride thin films. It was shown, that narrow NbN superconducting strips could be used forconstruction of ultrafast single photon detectors, which are expected to play important role in the secure quantum communications. Very recently, team from Montanuniversität Leoben succeeded in preparation of superconducting high entropy alloy (HEA) thin films and team from Slovak side preformed measurements of its superconducting properties. Preparation of nitride HEAs will be next step in effort to improve superconducting parameters of thin films for the purpose to be used in future quantum devices. |

| Supravodivé vlastnosti tenkých vrstiev boridov | |
| Superconducting properties of boride thin films | |
| Program: | Mobility |
| Project leader: | doc. RNDr. Flachbart Karol, DrSc., akademik US Slovenska |
| Annotation: | The aim of the mobility project is to prepare thin films of superconducting borides YB6 and ZrB12, and to investigate their properties as function of thickness, microstructure and applied pressure.The outcome of this investigation will be new information about how the superconducting properties of bulk (3D) superconductors change when they become two dimensional (2D). In this regard namely a modification of superconducting properties is expected due to a considerable change of rich phonon spectra in borides and of the related electron-phonon interaction, which are responsible for the origin of superconductivity. This research on borides is unexplored, therefore new and original results are expected.The project will, moreover, enable a mutual use of laboratory equipment (for thin film preparation in Leoben, for their investigation in Kosice), it will lead to promotion of post-docs and PhD students, to preparation of common publications, and probably also to further common projects. |

| MGFS – Kovové geometricky frustrované systémy | |
| Metallic geometrically frustrated systems | |
| Program: | Inter-academic agreement |
| Project leader: | doc. RNDr. Gabáni Slavomír, PhD. |
| Annotation: | The principal aim of this project is to establish the microscopic anisotropy parameters and the relevant terms for the magnetic interaction in MGFS. Despite significant experimental and theoretical work, such parameters are unknown for the compounds (e.g. TmB4, HoB4) which form a Shastry Sutherland lattice (SSL) as well as for the highly symmetric face centered cubic (fcc) lattice based systems (e.g. HoB12). The experimental approach will be magnetisation measurements as a function of field direction, neutron diffraction combined with modelling techniques like WIEN2K, McPhase or SpinW. The oscillatory RKKY exchange interaction parameters are expected to be susceptible to applied pressure as well as to alloying. Suitable methods and oriented samples of rare earth borides are available.Crystal field anisotropy is theoretically described by a multipole expansion of theelectric field. The crystal field level splitting parameters will be determined frommagnetisation and specific heat data, as a function of field direction, as well as frominelastic neutron diffraction on powder samples, typically using software like McPhase.The goal of this part is a description of anisotropy of TmB4, HoB4 and the symmetric fcc– counterparts HoB12 and TmB12.The second set of parameters needed for understanding of the Hamiltonian are themagnetic interactions. They will be determined from the dispersion relationsmeasured using neutron spectroscopy on HoB4 and HoB12 along differentcrystallographic directions and in applied magnetic field. These parameters depend ondetails of the RKKY interaction which as a cross check can also be obtained from firstprinciples, using packages like WIEN2K. This type of experiments will be carried out atthe HZB Berlin on isotopically enrich Ho11B4 and Ho11B12 samples, which are availableand first testing experiments were already carried out.We intend to verify results by high pressure experiments (we assume pressuresup to 10 GPa in diamond pressure cells) which is associated with the increase ofitinerant electron concentration in MGFS, and thus with the change of parameters aswell as changes of critical fields and temperatures. This aim will cover MGFS based onthe SSL structure as well as systems based on the fcc structure. Another option to verifyresults is alloying. We will study the effect of substitution of magnetic ions like Tm3+and Ho3+ ions by nonmagnetic Lu3+ ions. Necessary devices and samples for thisresearch are available. |

| Supravodivosť tenkých filmov boridov | |
| Superconductivity of boride thin films | |
| Program: | Bilateral – other |
| Project leader: | doc. RNDr. Flachbart Karol, DrSc., akademik US Slovenska |
| Annotation: | The aim of the proposed project is to prepare thin films of superconducting high-boron borides(YB6, ZrB12 and LuB12) and investigate their superconducting properties as function ofthickness, microstructure and of applied pressure. The outcome of this investigation will be newknowledge about how superconducting properties of bulk (3D) boride superconductors changewhen they become (quasi) two dimensional (2D). As a result, a variation of superconductingproperties is expected above all due the change of rich boride phonon spectra (and the relatedelectron-phonon interaction) when the structure changes from a 3D one to a 2D one. |

| Program: | Bilateral – other |
| Project leader: | RNDr. Mihalik Marián, CSc. |
| Annotation: | Proposed project is devoted to study of isostructural compounds of the type A2T2X, where A islanthanide, which represent group of materials with very well localised f-electrons, or uranium,which forms compounds with delocalised 5f electron states. T is transition element and X is nontransitionelement like Sn or In. In this system a principal shortness of modern solid statephysics to include related phenomena connecting with rise and development of magneticordering by ab-initio calculations of electron structure impose enhanced requirement onexperimental physics. The reason is dominancy of matched electron – electron interactions,which lead to exotic i.e. emergent phase like unconventional superconductivity or non Fermiliquid behaviour. These phenomena are not described very well in the frame of classical theoriesbased on the one – electron approximation.The scientific goal of the project is determination of characteristic features related to magneticphase transition in selected compounds of the type A2T2X, exploration and specification of newcompounds from this series, determination of hydrogen absorption and study of magneto -structural correlation in this system. Variable concentration of H will be used to tune magneticproperties around the onset of magnetic ordering (for U) or for tuning to the metal-insulator transition (for lanthanides). For compounds in the critical region of the transition, detailed characteristics down to very low temperatures will be established and analyzed in the context ofnon-Fermi liquid physics. The project has a good chance to give a significant contribution to thephysics of strongly correlated systems. A broader goal is a better coordination (integration) of the Czech and Slovak research teams working in the same field and their instrumental capacities. |

| Program: | VEGA |
| Project leader: | RNDr. Orendáč Matúš , PhD. |
| Annotation: | Borides form a broad class of materials with diverse physical properties. Metallic geometrically frustratedmagnetic tetraborides (REB4), where RE represents an element from the rare earth group, are quasi-2Dfrustrated systems with different anisotropy strength and the same crystal lattice. These systems form an idealenvironment for studying the connections between anisotropy and magnetization processes. With the help of thedeviation of the magnetic field from the easy axis of magnetization, it will be possible to observe thosecomponents of inter-spin interactions that do not appear when the field is oriented in the direction of the easyaxis, which will contribute to the development of more accurate theoretical models. By studying quantumoscillations in SmB6, which is considered to be a representative of strongly correlated topological systems, and in other selected hexaborides, it will be possible to contribute original results to the long-standing debate whetherSmB6 is a topological insulator or not. |

| Annotation: | Superconducting materials have become an integral part of the latest technologies such as quantum computers,single-photon detectors, magnetic resonance, SQUID, etc. Achieving room-temperature superconductivity is nomore the only goal, but targeted improvement of superconducting parameters (upper critical field, criticaltemperature) for application needs is the key. Extreme conditions in the form of very low temperatures, highpressures and reduction dimensions into quasi-two dimensions are very powerful tools in this endeavor. Inparticular, in case of thin films the superconducting properties can be tuned by several external parameters (e.g.film thickness, substrate, interfaces). The main goal of the project is to improve superconducting parameters ofthe high-entropy alloys and other materials in the form of thin films in purpose for use in future quantumapplications technology. |

| Magnetic frustration and superconductivity in 2D and 3D borides | |
| Program: | VEGA |
| Project leader: | RNDr. Pristáš Gabriel, PhD. |
| Annotation: | Borides form a wide class of materials with different physical properties. Metallic geometrically frustratedmagnetic tetraborides (REB4) are 2D frustrated systems and together with their fcc 3D counterpartsdodecaborides (REB12) pose an ideal playground for study of 2D/3D interplay of frustration in megnetic systems.Uniaxial pressure, as well as hydrostatic pressure will be the tuning parameters which can change the interactionbetween magnetic moments. Depending on the direction of uniaxial pressure we will be able to change themagnitude of interactions in different crystallographic directions and test theoretical predictions. A similarcrossover between 2D and 3D can be studied also in superconducting borides as YB6, ZrB12 and LuB12. Even ifthere exist at present time a rather good understanding of the physical properties of bulk metallic borides, thereare still serious open questions what will happen if one dimension will be reduced considerably – by preparingthin films of corresponding borides. |

| Project leader: | Mgr. Szabó Pavol, CSc. |
| Annotation: | Project aims at understanding of the effect of disorder on superconductivity in systems which are close to Superconductor-Insulator Transition as well as in thin films of hydrides. The thin films of MoN, MoC, TiN of various thickness and stoichiometry and on different substrates as well as polycrystalline and nanostructured boron-doped diamond will be prepared. Some of these systems reveal fermionic and some bosonic effects insuperconducting state. By means of conductance measurements from DC to optical frequency range as well as by means of the scanning tunneling microscopy and spectroscopy at very low temperatures and in high magnetic field we will address the question of what kind of superconductivity is established in strongly disorderd systems where already quasiparticles out of superconducting state reveal renormalized density of states around the Fermi energy. We want also to understand the appearence of superconductivity in thin films of hydrides. We will explore the effect of disorder changing upon hydrogen content, thickness of film, substrate, microstructure and applied pressure on superconductivity in YHx, TiHx, VHx hydrides and their oxyhydrides. |

| FRUSTKOM – Frustrované kovové magnetické systémy | |
| Frustrated metallic magnetic systems | |
| Program: | SRDA |
| Project leader: | doc. RNDr. Gabáni Slavomír, PhD. |
| Annotation: | The up to now experimental and theoretical studies of frustrated magnetic systems (FMS) has been concentrated mainly on dielectric systems. Such systems can be found in 2D and 3D lattices based on equilateral triangles, and in dielectrics the interaction between their spins can be relatively well defined and described. In metallic FMS (M-FMS), which have been much less studied, an important role plays the long-range indirect exchange interaction between the spins mediated by conduction electrons (the RKKY interaction). To the small number of up to now studied M-FMS belong also some rare earth metallic borides having a fcc (e.g.HoB12, ErB12) or Shastry-Sutherland (e.g.TmB4, HoB4, ErB4) structure. This project aims are to investigate experimentally the impact of high pressure (hydrostatic and uniaxial), the influence of alloying and the anisotropy on the magnetic, transport and thermal properties of M -FMS, which has not been studied yet. A pioneering work will be above all the direct observation of magnetic structures of individual phase diagram regions of these M-FMS by spin-polarized scanning tunnelling microscopy. Investigated will be also the dynamics of magnetic structures (the influence of the rate of change of the magnetic field on these structures) and the study of magnetic excitations (by neutron diffraction methods) in selected tetraborides and dodecaborides.The challenging experimental studies, for which both high quality samples and suitable methods are already available, will be supported by the theoretical interpretation of received results, and by the theoretical elaboration. |

| Annotation: | Strong correlations between free (conduction) and bound (localized) electrons in a condensed matter can be change or modified by extreme conditions (very low temperatures, high pressures and magnetic fields), what often leads to the creation of new/exotic states/effects in these materials. In this proposal, we will experimentally study the newest open problems in strongly correlated electron systems (SCES), as surface conductivity in topological Kondo insulators, dynamics of frustrated antiferromagnets, Kondo vs. spin-polaron model in spin glasses, superconductivity under pressure. All this will be a very time-consuming research on new-produced samples. |

| Annotation: | The project aims at understanding the problem of how superconductor transforms to insulator at increaseddisorder. The questions of what is the force driving the superconducting transition temperature to lower values inultrathin superconducting films and what is the mechanism of the quantum phase transition betweensuperconducting and insulating states will be addressed experimentally as well as theoretically. Thesuperconducting films of various content with thicknesses down to few atomic layers as well as thenanostructures and resonators on their basis will be prepared. Transport, microwave and optical properties ofthese objects will be investigated. By means of the subkelvin scanning tunnelling microscope the spectral mapsof the quasiparticle density of states at ultralow temperatures and in high magnetic fields will be measured. Wewill explore possibilities to prepare sensitive photon detectors and amplifiers based on ultrathin disorderedsuperconducting films for the spectroscopy in physics, chemistry and biology.Dynamics of the surface states in another macroscopic quantum object, the superfluid 3He which is thetopological insulator at ultra low temperatures, will be investigated experimentally as well as theoretically. Theobjective is to elucidate the dynamics of surface bound excitations in superfluid 3He by means of mechanicalresonators and resolve if the excitations can be identified with the long searched Majorana fermions.By experiment the recent question if samarium hexaboride is a topological insulator will be addressed. |

| Quantum phase transitions. Influence of chemical and hydrostatic pressure on selected rare earth borides. | |
| Program: | VEGA |
| Project leader: | doc. RNDr. Gabáni Slavomír, PhD. |
| Annotation: | Quantum phase transitions (QPT) occur at absolute zero temperature, T=0K, when some non-thermal parameterlike external pressure, magnetic field or chemical composition of material is changed, and causes a phasechange. These transitions from one ground state to another are driven by quantum fluctuations. At present, QPTin electronic and magnetic systems have attracted considerable attention thanks to new fundamental discoveriesand explanations of open questions (quantum Hall effect, non-Fermi liquid behavior of electrons, unconventionalsuperconductivity in magnetic materials). In this proposal, we plan to / will study especially the influence of highpressure and chemical composition on mostly magnetic rare earth borides at very low temperatures and inmagnetic fields. There are possibilities to observe the new (quantum) phases of materials and to explain theirphysical properties in the vicinity of so called quantum critical points (QCP) at mentioned extreme conditions(pressures up to 10 GPa, mK temp.). |

| Annotation: | The project contributes to the extension of bordes of knowledge in the field of nanoscopic magnetic systems. Specifically, the project focuses on several very actual aspects of nanomagnets such as size effects, influence of the crystal field, dipolar coupling, frustration, Dzyaloshinskii-Moriya interaction etc., on the ground-state and finite-temperature properties of isolated clusters. Another aspect is the investigation of the effect of inter-cluster coupling, which is always present in real materials and leads to the modification of the ground-state and finite-temperature properties of the clusters embedded into extended lattices. This real effect often induces novel cooperative phenomena. The attention is paid to novel relaxation mechanisms due to the coupling of the nanoscopic magnetic systems with other degrees of freedom. The project is also devoted to the influence of preparation methods and deposition techniques on the magnetic properties of the selected nanomagnets. |

| Annotation: | Centre of Low Temperature Physics and Material Research at Extreme Conditions Kosice, CLTP-MREC, represents a concept of cutting-edge experimental research institution focused on low temperature physics and material research under extreme conditions. By the extreme conditions apart from low temperatures meant are also high as well as extremely small magnetic fields, extremely high pressures and temperatures, and also reduced dimensions – preparation of nanomaterials and investigations of properties on a nanoscopic scale. Main goal of the project has been to mobilize a common research of constituting organisations and to target it to the area of materials and technologies with a high application potential and technological transfer. The world competitive physics and material science demands the up-to-date research infrastructure. CLTP-MREC has already now in disposal top level instruments and techniques obtained within the framework of the European structural funds, Framework Programmes and other grant schemes but as the most important added value the Centre deems its capability to develop own unique scientific methods, instruments and technologies. The Centre belongs to a dozen world laboratories able to perform experiments in microkelvin range but it disposes also other unique techniques for processing and characterization of materials in high magnetic fields, and at high pressures and temperatures. In this proposal we will concentrate on development of another top level instruments and technologies as well on a synergetic collaboration of our laboratories which represent an important base of the material R&D in Košice. |

| Annotation: | Phase transitions between different ground states of the material can be induced by altering the balance of competing interactions by changes in composition, pressure, or external applied magnetic field. Interplay between competing orders can lead to new materials with unexpected properties. For example it may stand behind the high temperature superconductivity. Within the project we will focus on fundamental studies in three classes of superconducting materials where the above mentioned competing orders can be put in a play: pnictides, superconductors based on doped semiconductors and dichalcogenides.The project represents a physical realization of the unique experimental basis of the Centre of Cryophysics and Cryonanoelectronics Košice-Bratislava built as a Centre of Excellence of the Slovak R&D agency during last years and supported by the Framework Programme and other projects. |

| Annotation: | At low temperatures, when thermal fluctuations are suppressed, condensed matter transforms to magnetically ordered or superconducting state. Magnetism and superconductivity are antagonist phenomena, yet there exist some examples of ferromagnetic superconductors. Indeed, interplay of superconductivity and magnetism stands among the most attractive up-to-date research topics. In the proposed project we intend to study selected magnetic and superconducting materials in extreme experimental conditions: very low temperatures, high magnetic fields, under high pressures and with space resolution down to atomic scale in order to clarify their fundamental physical properties.Partially we will focus on implementation and improvement of new experimental techniques and methods. Namely it is implementation of relaxation calorimetry at milikelvin temperatures, construction of high-pressure cell up to 100 kbar for measurements under pressure and implementation of local magnetization measurements using miniature Hall probes. |
