A Ferrimagnetic Order of CrSe₂ Monolayer Under Strain and Charge Doping

CrSe₂ monolayer is a recently synthesized ferromagnetic material exhibiting remarkable environmental stability. By using first-principles calculations, a comprehensive study on the magnetic phase diagram of CrSe₂ monolayer under conditions of electron/hole doping and different strains is presented. It is demonstrated that applying compressive strain can induce a magnetic phase transition from the ferromagnetic order to a Hexagon ferrimagnetic order. Moreover, the results reveal that electron doping can attenuate the ferromagnetism in the monolayer. This work thus provides insights into the design of CrSe₂-based spintronic devices.
