Two-dimensional Heisenberg models with materials-dependent superexchange interactions

Jia-Wen Li, Zhen Zhang, Jing-Yang You +2

The two-dimensional (2D) van der Waals ferromagnetic semiconductors, such as CrI${}_3$ and Cr${}_2$Ge${}_2$Te${}_6$, and the 2D ferromagnetic metals, such as Fe${}_3$GeTe${}_2$ and MnSe${}_2$, h…
