采用磁控溅射技术和退火工艺制备了FePt薄膜和[FePt/Ag] n多层膜。通过比较两种薄膜的微结构和磁性能，研究了Ag的添加对FePt薄膜结构和磁性能的影响。适量Ag的加入有助于在较低的退火温度下实现FePt的相变。随着Ag的添加，FePt薄膜的磁畴图案从迷宫状图案变成[FePt/Ag] n多层薄膜中更离散的岛状磁畴图案。此外，引入Ag阻碍FePt晶粒长大。FePt膜和[FePt/Ag] n多层膜中的深度缺陷证实了Ag的加入是由于[FePt/Ag] n膜中存在大量的钉扎缺陷，从而影响了其磁性能和微结构。
FePt thin films and [FePt/Ag]nmultilayer thin films were prepared by magnetron sputtering technique and subsequent annealing process. By comparing the microstructure and magnetic properties of these two kinds of thin films, effects of Ag addition on the structure and properties of FePt thin films were investigated. Proper Ag addition was found helpful for FePt phase transition at lower annealing temperature. With Ag addition, the magnetic domain pattern of FePt thin film changed from maze-like pattern to more discrete island-like domain pattern in [FePt/Ag]nmultilayer thin films. In addition, introducing nonmagnetic Ag hindered FePt grains from growing larger. The in-depth defects in FePt films and [FePt/Ag]nmultilayer films verify that Ag addition is attributed to a large number of pinning site defects in [FePt/Ag]nfilm and therefore has effects on its magnetic properties and microstructure.
