The Mn 2 Ge 2 Te 6 shows intrinsic ferromagnetic (FM) order, with Curie temperature ( c T ) of 316 K. The FM order origins from superexchange interaction between Mn and Te atoms. Mn 2 Ge 2 Te 6 is half-metal (HM), and spin-β electron is a semiconductor with gap of 1.462 eV. Mn 2 Ge 2 Te 6 tends in-plane anisotropy (IPA), with magnetic anisotropy energy (MAE) of -13.2 meV/f.u.. The Mn 2 Ge 2 Te 6 shows good dynamical and thermal stability. Moreover, Mn 2 Ge 2 Te 6 presents good ferromagnetic and…
