中文摘要	Fe-N films 2 mu m thick keep their excellent magnetic properties of 4 pi Ms = 2.2 T, Hc < 80 A/m when the nitrogen content is in the range of 5.9-8.5 at.% . These films meet the requirements of recording heads. Fe-N thin films were fabricated at different base pressure. It is found that the magnetic properties of those prepared in high vacuum are much better than those of films prepared in low vacuum. The coercivity of the former is 34. 8 A/m. The structural analysis showed that there are few defects and weak stress in the Fe-N films prepared in high vacuum, but many defects and strong stress in those prepared in low vacuum.
