Czech-Bavarian Mini-School: Magnets, Lasers, Neutrons

Our department in collaboration with Technical University of Munich organized the third edition of the Czech-Bavarian Mini-School on large research infrastructures and open data. Students acquired skills ranging from crystal growth to advanced neutron techniques and learned how to analyze data in accordance with F.A.I.R. principles.

Our colleague Petr Král awarded by the GAUK Board

Work of our valuable student and colleague Petr Král was awarded by the Charles University Grant Agency (GAUK) Board. His project “Pressure-driven structural and magnetic transformations in 221 intermetallics“ was evaluated as “Exceptionally good“ and moreover obtained a Honorable mention after his work has been evaluated as the third best solved project among the GAUK projects completed in 2023. The GAUK award was given to him within the festive ceremony on November 17 in Karolinum.

High-quality UTe2 single crystals pave the way for breakthrough PNAS study

Our recent paper published in PNAS reveals a significantly revised high magnetic field superconducting phase diagram in the ultraclean limit of UTe2 single crystals. The study demonstrates a pronounced sensitivity of field-induced superconductivity to the presence of crystalline disorder.

The Magnetism Group studies physical phenomena originating from the behavior of electrons in matter. Throughout the group, we prepare and study a range of materials ranging from: lanthanoid and uranium-based intermetallics, magnetic-shape-memory Heusler alloys, and frustrated magnetic oxides, to van der Waal and misfit layer materials. Using both our range of preparation and crystal growth facilities, as well as our extensive suite of properties measurements instruments, we are steadily building bridges-of-understanding linking the electronic structure of this wide range of materials to the observed magnetic and electronic properties. We also investigate the tuning of these properties using both high-magnetic fields and high pressures.
