Abstract
The effect of heat treatment on the magnetic properties of Tb-Co amorphous films and film structures based on them has been studied. Regularities of variations of the coercive force and induced magnetic anisotropy constants of Tb-Co amorphous films and the coercive force and unidirectional anisotropy field of the permalloy layer in Fe19Ni81/Tb-Co films were determined as functions of the annealing temperature. The regularities found have been interpreted by assuming temperature-induced changes in the shortrange atomic order in the amorphous structure and interlayer diffusion in two-layer films.
