Engineering 2D high-temperature ferromagnets with large in-plane anisotropy via alkali-metal decoration in a tetragonal CoSe monolayer
This study proposes that alkali-metal decoration of a tetragonal CoSe monolayer creates stable 2D ferromagnetic metals with room-temperature Curie temperatures and large in-plane magnetic anisotropy, establishing a viable strategy for high-performance nanoscale spintronics.
