Structure and properties of domain walls in a (111)-oriented plate of crystals with combined anisotropy

Abstract

We theoretically study the physical properties of magnetic domain wall inhomogeneities in crystals possessing both natural cubic and induced uniaxial anisotropies (combined anisotropy). The structure and stability of Bloch type domain walls (DWs) has been investigated for plates with (111)-oriented surfaces in the anisotropy constant range in which bubbles exist. We have shown the possibility of hysteresis phenomena during reorientation the DWs relative to crystallographic axes. Dynamic characteristics of steady and oscillatory motion have been found to be functions of sample material parameters and their peculiarities are examined in the vicinity of spin-reorientation phase transition as well as in the vicinity of the DW reorientation line phase transition relative to crystallographic axes. The dynamic DW parameter values are shown to be affected by temperature and external stresses.
