研究了Ag底层对FePT薄膜的微观结构和磁性能的影响。研究发现，Ag底层厚度是导致L10有序FePt(001)薄膜具有高垂直各向异性的重要因素。化学有序度随着银层厚度的增加而增加，在40 nm处达到最大值，然后随着银层厚度的增加而略有下降。初始磁化曲线和扫描电极显微镜结果表明，随着Ag厚度的增加，Ag/FePT薄膜的磁化反转机制由成核型转变为钉扎型/S-W旋转型。当Ag厚度从0增加到40 nm时，化学有序度的增加和磁化反转机制从成核态转变为钉扎态/S-W旋转导致了面外矫直力的增加。对于具有50 nm银层的样品，其面外矫顽力的降低可以归因于化学有序性的降低。
The effects of Ag under layer on the micro structural and magnetic properties of the FePt films were investigated. It was found that the thickness of the Ag under layer is very important factor to induce the L10 ordered FePt (001) films with high perpendicular anisotropy. The chemical ordering increased with increasing Ag layer thickness, reached its maximum at 40 nm, and then slightly decreased with further increasing Ag thickness to 50 nm. Moreover, the initial magnetization curve and the scanning electrode microscopy (SEM) results showed that the magnetization reversal mechanism of the Ag/FePt films changed from nucleation mode to pinning mode/S-W rotation with increasing the Ag thickness. The increase of the chemical ordering and the change of magnetization reversal mechanism from nucleation mode to pinning mode/S-W rotation led to the increase in out-of-plane coercivity when Ag thickness increased from 0 to 40 nm. For the sample with 50 nm Ag layer, the decrease in out-of-plane coercivity could be attributed to the decrease in the chemical ordering.
