Media dispersion regularizes singularities in defect and magnetization flows.

Inhomogeneity in the magnetic subsystem influences wave conversion processes.

Abstract

Dislocation waves in magnetic crystals in the vicinity of orientation phase transition (OPT) temperatures are considered in a frame of the field theory of the defects. The singularities of the dislocation flows, elastic deformations and magnetization occur if the magnetic subsystem is inhomogeneous and the dispersion of the media is not taken into account. Media dispersion causes a regularity of these parameters and a conversion of the spin wave to the dislocation wave.
