Magnetic materials are ubiquitous in current electronics, sensors and power systems. Their high tunability offers a multitude of new approaches to non-volatile data storage, high-speed information transfer, energy recovery, drug delivery and sensing. Understanding the dynamics and fundamental phenomena in nanomagnets is crucial for finding ways in which electronic and magnetic order can be efficiently controlled using the least energy possible.
The research is carried out in two closely collaborating groups:
- Nanomagnetism and Spintronics group at CEITEC
- CEITEC Nano
Highlights
19 May 2023: New publications (field concentrators, magnonics, FeRh)
Multiple articles have been published recently on various topics - magnetic field concentrators, magnonics, and FeRh metamagnets:
- Microscale metasurfaces for on‐chip magnetic flux concentration
- Observing high-k magnons with Mie-resonance-enhanced Brillouin light scattering
- Phase-resolved optical characterization of nanoscale spin waves
- Propagating spin-wave spectroscopy in a liquid-phase epitaxial nanometer-thick YIG film at millikelvin temperatures
- Magnetic-field-controlled growth of magnetoelastic phase domains in FeRh

3 November 2022 : Igor Turčan defended his PhD thesis; new group members (visiting researchers)
Igor successfully defended his doctoral thesis "Magnetism in curved geometries". We wish Igor good luck both in personal and further professional life at Thermo Fisher Scientific company and congratulate him on his recent promotion.
Further personal changes in the group
Friederike Ringe finished her internship. To balance the number of people, we now welcome 2 visiting researchers: Andrey Voronov (PhD student from University of Vienna) and Francisco Javier Peña Espinoza (UNAM, Mexico).
5 October 2022 : MetaMagIC project meeting in Liège
Within the CHIST-ERA project MetaMagIC, we took part in the project workshop at University of Liège. Jan Hajduček presented our results on TEM magnetic imaging of flux concentrators on SiN membranes.

15 September 2022 : Celebrating 10th anniversary of CEITEC with new preprints
While the 10th anniversary of CEITEC was already in 2021, only now we could celebrate it properly with other colleagues. Aside from listening to live folk music, our team members also took part in traditional Moravian dancing.
New preprints on metamagnets and magnonics are available:
- Preserving Metamagnetism in Self-Assembled FeRh Nanomagnets {FeRh islands}
- Observing high-k magnons with Mie-resonance-enhanced Brillouin light scattering {Magnonics}
