In Gd/Y, the interlayer exchange is an oscillatory function of the Y thickness. Now strong interlayer exchange effects have been found in many multilayered structures based on ferromagnetic transition metals such as Fe/Cu, Ag/Ni and Fe/Au multilayer films. The multilayer films based on Fe-N alloy attracted 收起
