摘要
The crystallographic and magnetic properties of Sm_(2) Fe_(17) N_(2) and Y_(2) Fe_(17) N_(2) have been investigated by using X-ray diffraction techniques and magnetic measurements.The effects of the interstitial nitrogen atoms on the Fe-Fe and R-Fe exchange interactions,iron 3d band structure and magnetocrystalline anisotropy induced by crystal field interactions in these nitride compounds are discussed.
