摘      要：Two-dimensional van der Waals magnetic materials are intriguing for applications in the future spintronics devices,so it is crucial to explore strategy to control the magnetic ***,we carried out first-principles calculations and Monte Carlo simulations to investigate the effect of biaxial strain and hydrostatic pressure on the magnetic properties of the bilayer CrI_(3).We found that the magnetic anisotropy,intralayer and interlayer exchange interactions,and Curie temperature can be tuned by biaxial strain and hydrostatic *** compressive biaxial strain may induce a ferromagnetic-to-antiferromagnetic transition of both CrI_(3) *** hydrostatic pressure could enhance the intralayer exchange interaction significantly and hence largely boost the Curie *** effect of the biaxial strain and hydrostatic pressure revealed in the bilayer CrI_(3) may be generalized to other two-dimensional magnetic materials.
