On a mechanism of nucleation in crystals with combined anisotropy

Abstract

The stable states of magnetic inhomogeneities of the “static”-soliton type in a (111) plate of a garnet ferrite with combined anisotropy are investigated theoretically, and the conditions for their occurrence are established. A model of static solitons is considered, and its fundamental properties are determined by solving the corresponding variational problem numerically. It is shown that these inhomogeneities originate at crystal defects and can significantly affect the kinetics of a phase transition of the spin-reorientational type.
