Annotation The article represents the results of a comprehensive study of the structural and phase state and magnetic properties of three-layer Co (Fe) / Gd (Dy) / Co (Fe) / S film systems before and after heat treatment. It is shown that the structural and phase state of Gd and Dy films depends on their thickness, and the processes of phase formation in three-layer films have a number of features. It is established that magnetic properties of film systems correlate with their structural and phase state, leading to a change in the coercive force and residual magnetization and the nature of the dependences between the film magnetization and the applied external magnetic field.
