Sm─FeCo─N合金薄膜的磁性与微观结构

Microstructure and Magnetic Properties of Sm FeCo N Films

采用离子注入方法制备Ｓｍ－ＦｅＭ－Ｎ磁性合金薄膜，研究少量Ｃｏ部分取代Ｆｅ对薄膜磁性能的影响，探索研究Ｓｍ－ＦｅＭ－Ｎ磁性材料的新途径．实验发现：Ｃｏ＋注入使样品的饱和磁化强度明显增加，Ｓｍ－ＦｅＣｏ－Ｎ薄膜的饱和磁化强度是Ｓｍ－Ｆｅ－Ｎ薄膜的１．６倍．经ＴＥＭ分析。

Sm FeM N magnetic alloy films were prepared by an ion implantation method. It is a new way to prepare magnetic thin films. The effects of Co on structure and magnetic properties of Sm FeCo N film were studied. The results show that saturation magnetization of the sample greatly increases with Co + implanted. The saturation magnetization of Sm FeCo N is 1 6 times as much as that of Sm Fe N. Co + doesn′t form compound with Fe or Sm.
