Outcome of large international cooperation published in Nature Communications

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 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.
