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.

NanoSky – Skyrmióny vo feromagnetických nanoobjektoch
Skyrmions in ferromagnetic nanoobjects
Program: SRDA
Project leader: RNDr. Cambel Vladimír DrSc.
Annotation: In this project we will focus on the numerical and experimental study of skyrmions in ferromagnetic nanoobjects. The skyrmions were found in structures with multilayer configuration and the confinement due to geometry can increase stability of the skyrmion significantly. Thus nanoobject structures can lead to room temperature stable, reconfigurable magnetic elements. Still a control and experimental investigation of such structures is chalenge. We will concentrate on the facilitation of generation and develop methods for identification and characterization of the skyrmion states. The study will pave the way towards the implementation of skyrmion in magnetic devices based on the patterned nano-objects (single or arrays).

Spinové vlny v exotických štruktúrach
Waves in exotic spin textures
Program: SASPRO
Project leader: Dr. Mruczkiewicz Michal
Annotation: The research project is focused on thetheoretical investigation of collective excitations in various magnetic architectures and magnetic field configurations (spin textures). In particular, the dynamical properties of magnetic vortices and skyrmions will be studied in disks, nontrivial geometries and ultrathin films. Possible mechanisms of excitations (e.g., current or external field) will be considered and the possibility of experimental verification of numerically studied structures will be evaluated. An important part of the work will be dedicated to the study of collective skyrmion modes, a topic of research that is completely unexplored yet. On the basis of the obtained results a logic device will be proposed.
Duration: 4.1.2016 – 31.12.2018
