| 摘 要： | 采用磁控溅射方法在玻璃基片上制备了[Ag／CoPt]n／Ag薄膜，并在600℃退火30min．结果表明，Ag掺杂厚度（x）对CoPt薄膜的结构和磁性影响很大．当Ag层厚度为0．5nm时，薄膜的垂直取向程度最高，其垂直矫顽力高达8．68×10^5A·m^-1而平行矫顽力仅为0．54×10^5A·m^-1．适当厚度的Ag不仅有利于薄膜的垂直取向，而且能降低晶粒间的交换耦合作用．

| Abstract: | [BN/CoPt]n/Ag composite films were grown on glass substrates by using magnetron sputtering, then annealed at 600℃ for 30min. The results show that the Ag thickness had the great effects on the magnetic properties and structures of the CoPt films. The [Ag（xnm）/CoPt（3nm）]5/Ag（10nm） film with x=0.5nm had a high perpendicular coercivity of 8.68×10^5A·m^-1 and a low in-plane coercivity of 0.54×10^5A·m^-1, which indicated a strong perpendicular anisotropy. The optimal Ag layer thickness not only promoted the perpendicular orientation of the films, but also reduced the intergrain exchange interactions of the films. |
