Nonlinear dynamics of vortex-like asymmetric domain walls in magnetic triaxial films

On the basis of numerical solution of the Landau–Lifshitz equation, we investigated the nonlinear dynamic behaviour of 90-degree and 180-degree asymmetric vortex-like domain walls in single-crystal films with cubic symmetry. Films with surfaces of (100) and (110) types are considered. The nonlinear dynamic rearrangement of the internal structure of a wall was investigated. The surface uniaxial magnetic anisotropy is shown to strongly influence the very process of dynamic rearrangement in the internal structure of a wall even up to the complete suppression of the whole process.
