Manipulation of saturation magnetization and perpendicular magnetic anisotropy in epitaxial Co$$_{x}$$Mn$$_{4-x}$$N films with ferrimagnetic compensation

Spintronics devices utilizing a magnetic domain wall motion have attracted increasing attention, and ferrimagentic materials with almost compensated magnetic moments are highly required to realize the fast magnetic domain wall motion. Here, we report a key function for this purpose in anti-perovskite Co$$_{x}$$Mn$$_{4-x}$$N films. Perpendicular magnetization emerges for $$0.8 leq x$$, and the saturation magnetization reaches a minimum value at $$x = 0.8$$.
