Study on the effects of strain and electrostatic doping on the magnetic anisotropy of GaN/VTevan der waals heterostructure.

Using a first-principles approach, this study delves into the effects of strain and electrostatic doping on the electronic and magnetic properties of the GaN/VTevan der Waals (vdW) heterostructure. The results reveal that when the GaN/VTevdW heterostructure is doped with 0.1/0.2of electrostatic charge, its magnetization direction undergoes a remarkable reversal, shifting from out-of-plane orientation to in-plane direction. Therefore, we conduct a thorough investigation into the influence of electron orbitals on magnetic anisotropy energy. In addition, as the strain changes from -1% to 1%, the 100% spin polarization region of the GaN/VTevdW heterostructure becomes smaller. It is worth noting that at a doping concentration of 0.1, the GaN/VTevdW heterostructure has a Curie temperature of 30 K above room temperature. This comprehensive study provides valuable insights and provides a reference for analyzing the electronic and magnetic properties of low-dimensional systems.
