论文摘要
MN2GE2TE6显示了内在的铁磁（FM）阶，居里温度（TC）为316K。FM顺序源来自Mn和Te原子之间的superexchange相互作用。 MN2GE2TE6是半米（HM），旋转 - \ b {eta}电子是一个半导体，间隙为1.462 eV。 MN2GE2TE6趋向于面内各向异性（IPA），磁各向异性能（MAE）为-13.2 Mev/f.u .. MN2GE2TE6显示出良好的动力学和热稳定性。此外，MN2GE2TE6在电荷掺杂下提出了良好的铁磁和半金属稳定性。载体掺杂可以有效调整磁性和电子特性。具体而言，可以有效调节磁矩，交换参数和MAE。总磁矩随掺杂的电荷线性变化。交换参数可以由掺杂载体控制。通过更改TE原子的PY和PZ轨道之间的杂交，掺杂载体可以将MAE调节为-18.4（+0.4 E），-0.85（-1.6 E），1.31（-2.4 E）MeV/F.U。具有固有的铁磁，高可调的MAE，良好的铁磁稳定性和半金属性的MN2GE2TE6可以帮助研究人员研究其在电子和旋转中的广泛应用。
The Mn2Ge2Te6 shows intrinsic ferromagnetic (FM) order, with Curie temperature (Tc) of 316 K. The FM order origins from superexchange interaction between Mn and Te atoms. Mn2Ge2Te6 is half-metal (HM), and spin-\b{eta} electron is a semiconductor with gap of 1.462 eV. Mn2Ge2Te6 tends in-plane anisotropy (IPA), with magnetic anisotropy energy (MAE) of -13.2 meV/f.u.. The Mn2Ge2Te6 shows good dynamical and thermal stability. Moreover, Mn2Ge2Te6 presents good ferromagnetic and half-metallic stability under charge doping. The carriers doping could effectively tune magnetic and electronic properties. Specifically, the magnetic moment, exchange parameter, and MAE could be efficiently tuned. The total magnetic moment changes linearly with charges doping. The exchange parameters could be controlled by the doping carriers. The carriers doping could modulate MAE to -18.4 (+0.4 e), -0.85 (-1.6 e), 1.31 (-2.4 e) meV/f.u., by changing hybridization between Te atoms' py and pz orbitals. Mn2Ge2Te6 with intrinsic ferromagnetism, high tunable MAE, good stability of ferromagnetism and half-metallicity could help researchers to investigate its wide application in the electronics and spintronics.
