Functional magnetic materials with perovskite structure based on rare earth and transition metal oxides | |
Program: | VEGA |
Project leader: | RNDr. Mihalik Marián, CSc. |
Annotation: | Part of our project deals with multiferroic materials and another with functionality of materials with perovskitestructure in respect to hydrogen storage or application of colloid with nanoparticles for hyperthermia. The projectis targeted to substitutional solid solutions and construction of magnetic phase diagrams in RTO3 system (R = Nd, Pr, Sm, Tb, Dy and T = Ti, Cr, Mn, Fe). Oxygen content affects physical properties of this system. The defect structure can be used for hydrogen storage. Experimental techniques like crystal growth of single crystals, synthesis of magnetic nanoparticles and study of various physical properties are complemented by theoretical approach using Density functional theory. Our project serves as starting point for re-examining the effect of oxygen content on physical properties of RMnO3 multiferroic compounds. The concept of storing hydrogen in the vacancies in these compounds is novel as well smart hyperthermia based on colloid containing magnetic nanoparticles of manganites. |

Structuralization phenomena in systems with nanoparticles | |
Program: | SRDA |
Project leader: | doc. RNDr. Kopčanský Peter, CSc. |
Annotation: | The structuralization phenomena plays key role in fundamental as well as in applied research. The proposed project is devoted to the study of the influence of nanoparticles on the structuralization phenomena in various systems as well as on the structuralization of the nanoparticles alone. Some special kinds of nanoparticles will be prepared, which will be used for study these effects. The main aim is to study the influence of the nanoparticles on the structuralization phenomena in two different kind of systems as liquid crystalline mater and amyloid structures. In the first system the magnetic particles can increase the sensitivity of liquid crystals on an external magnetic field. In the amyloid structures the nanoparticles can significantly influence the amyloid aggregation of proteins, which is responsible for amyloid diseases as Alzheimher, Parkinson and Dibetes II The prepared nanoparticles will also be used to build their 3D structures (metamaterials), i.e. to create systems with unusual physical properties as for example negative reflection. |
