Large magneto-optical effect and magnetic anisotropy energy in two-dimensional metallic ferromagnet Fe${}_3$GeTe${}_2$

Ming-Chun Jiang, Guang-Yu Guo

Few layers Fe${}_3$GeTe${}_2$ is currently the only atomically thin ferromagnetic metal, and thus has drawn huge attention in the field of two-dimensional (2D) magnetism. In this paper…
