Systematic studies have been performed on the layer-thickness dependence of magnetization and anisotropy for amorphous rare-earthtransition-metal compositionally modulated films with characteristic bilayer thicknesses () in the 0.63-nm (630 A) range. The results permit for the first time the development of a detailed model for the magnetization and perpendicular magnetic anisotropy as a function of . Single-ion anisotropy is shown to be the major contributor to the perpendicular anisotropy for Dy/Co and similar systems.
