摘要：

The magnetic material Sm2Fe17Nx (0<x<6) can be prepared by reacting Sm2Fe17 in an NH3-H-2 mixed gas atmosphere. As a fine powder, Sm2Fe17Nx (x=3.0-3.2) exhibits the characteristics of single magnetic domain particles. The oxygen content of the particle increases to about 5 at.% with increasing specific surface area, but such an oxidized region is largely confined to an outer layer of the particle. The thickness of the O-rich layer is about 10 nm, as observed by transmission electron microscopy and Auger electron spectroscopy.
