| Robustné spinové vlny pre budúce magnonické aplikácie | |
| Robust spin waves for future magnonic applications | |
| Program: | SRDA |
| Project leader: | Dr. Mruczkiewicz Michal |
| Annotation: | In this project we will focus on the theoretical and experimental investigation of spin wave dynamics at nanoscale. Spin wave is considered as candidate for an information carrier in ultrafast and energy efficient information processing devices. It is due the unique properties of spin waves, namely low heat dissipation, possible manipulation at nanoscale or reconfigurability. We are going to investigate specific spin wave systems, that can host robust, unidirectional and reprogrammable spin waves. Therefore, the results of this project will contribute to the field of modern magnetism, magnonics. |

| Adaptácia algoritmu metadynamiky na problémy mikromagnetizmu | |
| Application of the metadynamics algorithm to micromagnetism | |
| Program: | VEGA |
| Project leader: | Ing. Tóbik Jaroslav, PhD. |
| Annotation: | The subject of micro-magnetism studies are phenomena which are possible to describe on classicallevel of the theory. Micromagnetism describes processes in devices like bit-patterned media in harddisks,magnetic memories, magnetic radio-waves detectors, or bio and medical applications. Typicaldimensions of the devices active parts are order from micro-meter to few nanometers. Typical operationtemperature is room temperature. Usual model for these condition is classical physics. The mainproblem of the magnetic state stability simulation is the time-scale on which the magnetic statetypically persist. The magnetic state in memories is stable for years. There are several effectivealgorithms for finding lowest energy paths among metastable states. In order to search for stablemagnetic states effectively, we decided to implement matadynamics algoritm into micro-magneticsolvers. |
