Štúdium dynamiky magnetického víru pre využitie v súčiastkach
Study of magnetic vortex dynamics for device applications
Program: VEGA
Project leader: Ing. Šoltýs Ján, PhD
Annotation: In this project, we will focus on the theoretical and experimental investigation of magnetic vortices. The idea is touse them as a candidate for an information carrier in ultrafast and energy-efficient devices. The key idea of suchmemory is to use the two vortex core polarities as a magnetic bit that can be easily read and written via thedynamical reversal. We will search for the optimal shape of a magnetic 3D pattern with polarity easily controlledby a small in-plane magnetic field. In the second part of the project, we will design and prepare a system ofordered magnetic nanoelements in the vortex state set by an in-plane magnetic field. Such ordered nanoelementscan be considered as a single unit cell of the magnonic crystal. They can be also periodically arranged into afinite 2D array of interacting magnetic objects to observe the unidirectional spin waves. Therefore, ourinvestigation will be an important step towards the first experimental demonstration of topological magnons.

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.

Senzory na báze nosníkových štruktúr
Cantilever based sensors
Program: VEGA
Project leader: Ing. Šoltýs Ján, PhD
Annotation: Cantilever-based sensors are used for the detection of physical, chemical, and biological analytes. In principle, every external perturbation of magnetic, electrical, thermal, or chemical origin can be transducted into mechanical motion. A cantilever deflection can be measured with extremely high sensitivity and selectivity. The project aims to develop new techniques for modification of commercial scanning force probes and to produce new cantilever-based sensors. The key enabling technology of the novel sensors is focus ion beam ablation and on-chip electron beam lithography. Application of such techniques in cantilever sensing opens new functionalities of the cantilever, which can be used for sensor applications and research purposes in physics and biomedicine.
