Abstract :
The author reports the dependence of the magnetization, anisotropy constant, and Kerr rotation on the Fe concentration in FexCo 1-x/Pd multilayer thin films, where the Fe concentration x varies between 0 and 100% with maintaining the same sublayer thicknesses of 2 Å FeCo and 9 Å Pd. Perpendicular magnetic anisotropy existed for the films having Fe concentration less than about 80 atomic percent. Enhanced magnetization, possibly due to the polarization of Pd, was observed in the full range of Fe concentration. No simple proportional relation between the Kerr rotation and the magnetization was observed in this system
