Topological excitation dynamics in the high-temperature ferromagnet Fe3GaTe2

Abstract: Magnetic van der Waals systems are 2D crystals containing magnetic elements, and thus exhibit intrinsic low-dimensional magnetic properties. These cleavable materials provide a platform for exploring magnetism in the 2D limit, where a range of new phenomena are expected. The recent discovery of high-temperature ferromagnetism in Fe3GaTe2 at T > 350 K has been a considerable boost to the study of van der Waals magnets, as has the suggestion that skyrmions can be stabilized under certain conditions at relatively high temperature. This material resembles the well-studied system Fe3GeTe2, but has a considerably higher transition temperature. As part of a project to investigate this, and related, systems, we propose muon measurements of its magnetic transitions, concentrating on the low-energy dynamics expected in their vicinity, along with those occurring at low temperature and in sizeable applied fields.
