Özet

Functionalization of 2D magnetic materials is the modification of their surface to change their electronic, optical, mechanical, and magnetic properties. Altering the magnetic anisotropy of these materials by functionalization can lead to tunable magnetic properties for applications in magnetic data storage, spintronics, and magnetic sensors. We have investigated the effects of adsorbing fluorine and chlorine on the magnetic anisotropy properties of a monolayer of ferromagnetic CrN using first-principles calculations and a spin Hamiltonian. The results show that the magnetization axis of the monolayer shifts towards the in-plane direction due to the suppression of the orbital moment. We have also found that half-coverage of CrN is dynamically stable and has ferromagnetic ordered at room temperature.
