Our group used a unique capability of the X-ray magnetic circular dichroism technique to determine the magnetic orbital moment component of Vanadium ions in the layered van der Waals system. We have revealed an exceptionally sizable orbital moment of Vanadium ion resolving the long debate on this issue.
An electron and a hole can create bound states known as excitons. When these states occur in an atomically thin semiconducter layer, they behave like two-dimensional hydrogen atoms. Well, not exactly. Find more details in our recent paper.
We have organized Czech-Bavarian Mini-school on Large Scale Facilities and Open Data for the second time. The 15 students enjoyed magnetism, crystal growth, beer, collaborations, card games, and unicorns!
Materials called transition metal dichalcogenides can hold electrons in band minimas called valleys. We have investigated the possibility to control these electronic states by light pulses. Find the thorough theoretical analysis in our recent paper!
On December 7, the dean’s prize for the best bachelor thesis was awarded to our user Kateřina (Katka) Tetalová. In her thesis with the title “Morphology and physical properties of misfit layer compound VPbS3“, she focused on the properties of cleaved surfaces and exfoliated flakes. She performed detailed atomic force microscopy (AFM) studies to show the surface stability and the possibility to exfoliate single or few-layer flakes on SiOx and fresh Au surfaces.
The luminescence spectrum of excitons in ReS2 resembles the transitions in a free atom (Rydberg series), except that some transitions are missing, they are “dark”. This is due to interactions, as detailed by the theoretical calculations of A. Slobodenyuk, and verified by measurements in magnetic fields. Find more details in our recent paper.
We welcome Dr. Athanasios Koliogiorgos and wish him a successful post-doctoctoral stay
The results of Petr Král, Ph.D. student at the Department of Condensed Matter Physics, obtained within the MGML infrastructure were presented at the International Conference on Solid Compounds of Transition Elements 2022 held in Bordeaux, France. Petr was awarded a Best Poster prize for the communication entitled “Pressure effect on R2Cu2In intermetallics”.

We explored magnetic and structural properties of multifunctional chiral nanocomposites based on magnetic nanoparticles and achiral liquid crystals. Our magnetoresponsive nanoparticles provided a stable nanocomposite when dispersed in achiral liquid crystals, giving rise to chiral supramolecular structures that can respond to UV-light illumination.
