Effect of magnetization of the rare earth sublattice on the domain structure of a two-layer ferrite-garnet film

The temperature behavior of the domain structure in a two-layer ferrite-garnet film with one of the layers having a compensation point T _c , as well as in single-layer witness films, has been experimentally investigated. It is shown that the rare earth sublattice affects phase transitions in the domain structure of a two-layer film. The phase transitions observed were explained in terms of the concept of magnetostatic pressure in the domain structure.
