Magnetic anisotropy energy of ferromagnetic shape memory alloys Ni2X(X=Fe, Co)Ga by first-principles calculations

AIP Advances, 2017
First-principles calculations were employed to explore magnetocrystalline anisotropy energy (MAE) of Ni2X(X=Fe, Co)Ga alloys. The MAE of Ni2FeGa is found to show a concave behavior as a function of tetragonal distortion and easy-axis of magnetization in ...

Strain Engineering of Magnetoresistance and Magnetic Anisotropy in CrSBr

Advanced Materials, EarlyView.
Biaxial compressive strain significantly enhances magnetoresistance and critical saturation fields in thin flakes of the 2D magnet CrSBr, along all three crystallographic axes. First‐principles calculations link these effects to strain‐induced increases in exchange interactions and magnetic anisotropy.
