| Hierarchi of phase transitions in cooperative systems with spin-interactions: Towards emergent time-scales for read-heads | |
| Program: | Inter-academic agreement |
| Project leader: | RNDr. Mihalik Marián, CSc. |
| Annotation: | A broad variety of interactions pertaining to magnetic ions in a crystal field, gives rise to a succession of phase transitions under cooling across the Curie temperature. Conventionally, such transitions are triggered by a change of ambient conditions, such as temperature, pressure, and magnetic or electric fields. Controlling a phase of matter by excitations at different time scales may have amazing consequences for further recording and information processing, pushing these technologies into the range of unprecedented frequencies. Magnetic H-T phase diagrams of such materials are featured by poorly understood regions of multiple relaxation times, which often signify the spin-glass state. As such, they will be studied within this project activity for low-dimensional antiferromagnets with concurrent exchange interactions. Ising spin-glasses in transverse magnetic field will gain special consideration by means of dynamic susceptibility, ferromagnetic and electron-spin resonance measurements at low temperatures for manifestation of quantum effects. Irreversibility lines in H-T diagrams will be analyzed with focus on crossovers for a variety of multiferroic materials. The obtained ample data should reveal universal features of phase transitions apt to spin-glass behavior in magnetic and related materials. The results should be used for recommendations to novel materials of top-level information technologies. |

| 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. |

| Anisotropy of magnetoelectric coupling in rare-earth | |
| Program: | SRDA |
| Project leader: | RNDr. Mihalik Marián, CSc. |
| Annotation: | Magnetoelectric multiferroics are compounds wherein beyond coexistence of long-rangemagnetic and electric polar orders, magnetic and polar degrees of freedom are intrinsicallycoupled. Best examples are rare-earth manganites, whose magnetoelectric effect is associatedwith the competition between AFM and FM exchanges. Their magnetoelectric coupling has beenfrequently studied, though its origin is not fully understood, like its strong anisotropic nature. Tobetter understand this issue, TbMn0.08Fe0.02O3, and DyMn0.08Fe0.02O3 single crystals willbe grown and studied. Iron substitution of manganese already at low concentrations is known toenhance the magnetoelectric coupling. Since iron, contrarily to manganese, is magneticallyisotropic, novel effects in magnetoelectric anisotropy are expected to occur. To unravel thenature of such effects, a study of structure, lattice dynamic, magnetic, thermal and ferroelectricproperties will be carried out as a function of temperature for different magnetic field directionswith respect to crystallographic directions. |

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. |

Interplay between competing orders can lead to new materials with unexpected properties. For example it may stand behind the high temperature superconductivity.
