Our recent paper published in the Proceedings of the National Academy of Sciences (PNAS), titled “Superconducting critical temperature elevated by intense magnetic fields,” explores how intense magnetic fields influence superconductivity in unconventional systems, shedding new light on the physics of superconductors.
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.
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.
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.
Ondřej Michal, our Mgr. student, was awarded the Best Poster Award at the 22nd International Conference on Magnetism in Bologna for his poster titled "Magnetism and anisotropy of vdW antiferromagnet VCl3".
Our Ph.D. student Dávid Hovančík was awarded the Milan Odehnal Prize (2nd place) for his contribution to the investigating two-dimensional orbital magnetism in van der Waals systems. Dávid succeeded in the competition with his work published in Nano Letters, J. Phys. Chem. Letters, and Phys. Rev. B. Honorable Mention was in addition given to our another colleague, Petr Král for his study of magnetism and structure in frustrated tetragonal intermetallics with application of pressure.
The annual Scientific Members Meeting of the Institute Laue-Langevin (ILL; Grenoble, France) was organized at the Burg Obbendorf in a close proximity of the Jülich Forschungzentrum, Germany. Czech Republic was represented by our colleague Milan Klicpera.
The Magnetism Group is pleased to announce the 24th International Conference on Solid Compounds of Transition Elements (SCTE24). The conference will take place from June 17 to June 21, 2024, at the Hotel Duo in Prague. Dr. Ross H. Colman is honored to serve as the conference chair.
Since 2020, a new branch of magnetic materials, altermagnets, has been theoretically identified, in addition to the conventional ferromagnets and antiferromagnets. The exclusively distinct spin-symmetry characteristics of altermagnets are the opposite-spin sublattices connected by a real-space rotation, but not connected by a translation or inversion. Such symmetry has unconventional physical consequences.
Dr. M. Vališka’s team has successfully prepared high-quality single crystals of UTe2 specifically tailored for quantum oscillation studies. Utilizing these samples, the Cambridge group, led by A. Eaton, conducted a series of experiments in high magnetic field facilities, followed by advanced modelling to assess the potential geometries of Fermi sheets in UTe2.
