磁性材料 :具有高饱和磁化强度的氮化铁薄膜 ,其耐蚀性和耐磨性也非常优越 ,是适于磁头和磁记录媒体用的很有前途的新材料。Ｆｅ16 Ｎ2 的磁感应强度高于纯铁和 4 5%Ｃｏ Ｆｅ(分别为 0 7Ｔ和 0 4Ｔ)。Ｆｅ Ｎ梯度薄膜所含Ｆｅ和Ｎ的原子浓度随薄膜衬底到表面距离的变化而改
Magnetic Materials: Iron nitride films with high saturation magnetization are excellent in corrosion resistance and abrasion resistance. They are promising new materials for magnetic heads and magnetic recording media. The magnetic induction of Fe16 N2 is higher than that of pure iron and 45% CoFe (0 7T and 0 4T, respectively). The atomic concentration of Fe and N contained in the Fe N gradient film changes with the distance from the film substrate to the surface
