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 CoMnN films. Perpendicular magnetization emerges for , and the saturation magnetization reaches a minimum value at .
