STRUCTURE AND PROPERTIES OF DOMAIN-WALLS IN A (111)-ORIENTED PLATE OFCRYSTALS WITH COMBINED ANISOTROPY

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 stabil ity of Bloch type domain walls (DWs) has been investigated for plates with (Ill)-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. Dynami c 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 we ll as in the vicinity of the DW reorientation line phase transition re lative to crystallographic axes. The dynamic DW parameter values are s hown to be affected by temperature and external stresses.
