Enhanced ferromagnetism, perpendicular magnetic anisotropy and high Curie temperature in the van der Waals semiconductor CrSeBr through strain and doping

The pristine CrSeBr monolayer has an easy-plane magnetic anisotropy, although a tiny in-plane biaxial strain of 0.8% and a hole density of 5.31 × 10 13 cm −2 could change the orientation of the easy-axis to out-of-plane.
