摘要：

The magnetic properties of the Au(40 nm)/[FexCo1-x/Au](n)/Au(20 nm) system has been investigated. Perpendicular magnetic anisotropy (PMA) increases with increasing Fe atomic percentage x in the range of 0 < x < 50%, while the saturated magnetization (M-s) decreases slightly. Spin-reorientation in Fe30Co70/Au multilayers occurs around 0.9 nm FeCo. Moreover, K-eff can be tuned by the thickness of Au spacer layer. PMA obtained in Au(40 nm)/[Fe30Co70/Au(15 nm)](20)/Au(20 nm) multilayers is twice as strong as Au(40 nm)/[Fe30Co70/Au(3 nm)](20)/Au(20 nm), which indicates that the interface stress plays a crucial role for PMA in our sample.
