Abstract :
Sm-Fe-N films have been made by DC magnetron sputtering and heating in-situ in a nitrogen atmosphere. It is observed that the anisotropy changes from perpendicular to in-plane by nitrogenation. The Curie temperature is about 380 K. Aspects of structure, hysteresis loops, initial magnetization curves, and temperature dependence of coercivity are discussed
