    Abstract

    The dependence of perpendicular magnetic anisotropy on temperature and composition has been investigated for various (Fe,Co)-rare-earth amorphous binary alloy films prepared by evaporation. The temperature dependence of the perpendicular magnetic anisotropy is proportional to the third power of the rare-earth sublattice magnetization. The perpendicular magnetic anisotropy consists of two terms related to concentration. One is proportional to the rare-earth content and the other to its square. Both terms can be explained by a large rare-earth single-ion anisotropy.
