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.
The collaborative project of the Institute of Physics of the AS CR, v.v.i. and the Department of Condensed Matter Physics entitled “Computational design of high-performance ferroelectrics” was awarded by the Czech Science Foundation (GAČR).
Dávid Hovančík a Ph.D. student at the Department of Condensed matter physics is the leading author of the paper Robust intralayer antiferromagnetism and tricriticality in the van der Waals compound VBr3 selected as Editors' choice in PRB. This study is the result of a large collaboration between experimentalists and theoreticians from the Department of Condensed Matter Physics, Department of Inorganic Chemistry, Physical Institute of the Czech Academy of Science, Hochfeld-Magnetlabor Dresden, and MGML.
The discovery of LK-99, a gray-black compound with the potential to exhibit room-temperature superconductivity, captured the imagination of the scientific community and beyond. LK-99 has ignited a fervent pursuit to understand and validate its unique properties. This article traces the journey of our department as we embarked on a mission to replicate and comprehend the elusive behavior of LK-99. From its origins in a Korean research team's efforts to its controversial claims and replication attempts, we delve into the scientific intrigue surrounding LK-99 and its implications for the world of materials science.
On 15/6-18/6, we organized the 14th annual conference Prague Colloquium on f-Electron Systems (PCFES). The participants comprised colleagues interested in the physics of lanthanides and actinides, from many countries around the world, from Canada and Argentina to Japan. Among the diverse topics, the unconventional superconductivity of the compound UTe2, discovered in 2019, and the properties of other uranium tellurides dominated. The extreme resistance to magnetic field and the existence of several separate superconducting phases promises to shed new light on the very principles of superconductivity.
Ross Colman as a head of the Group of magnetism organizes regularly a Garden party. An informal meeting at the Tuchotice yard took place this year for the third time already and promisingly creates a tradition of meetings the members of our group in a friendly and relaxing atmosphere.
