Prediction of High Curie Temperature, Large Magnetic Crystal Anisotropy in 2D Ferromagnetic Co${}_2$Ge${}_2$Te${}_6$ Monolayer and Multilayer

Zhaoyong Guan, Ziyuan An, Yuzheng Jiang +3

The Co${}_2$Ge${}_2$Te${}_6$ shows intrinsic ferromagnetic (FM) order, which origins from superexchange interaction between Co and Te atoms, with higher Curie temperature ($T_c$) of 161…
