Inhomogeneous states of ferrite-garnet crystals with mixed anisotropy have been studied. A mechanism for the occurrence in these crystals of new types of magnetic inhomogeneities, “frozen solitons” or 0° domain walls, is presented. Their stability, static properties, and connection with homogeneous metastable states are investigated. The influence of the metastable states on the structure of domain walls of a normal type is also shown.
