Chromium-based transition metal dichalcogenides (TMDs) have attracted significant attention as an excellent candidate of atomically thin ferromagnetic materials with high Curie temperatures. However, the fabrication of Cr-based TMD atomic-layer films depending on the chalcogen atoms and their detailed electronic states have not been reported yet, and their physical properties remain unclear. In this talk, we will demonstrate sample fabrication methods of monolayer CrS₂ using MBE and topotactic methods, and report the results of high-resolution ARPES and XMCD experiments.
