Asymmetric vortex-chain domain walls in triaxial magnetic (110) films

Vortex-like structures of domain walls in triaxial magnetic (110) films are studied within a strict micromagnetic approach and a two-dimensional magnetization distribution approximation by numerically minimizing the total energy functional that includes all main types of interactions, among them the exchange, mag-C, netic-anisotropy, and dipole-dipole (in the continuum approximation) interactions. It is demonstrated that, because of the unusual anisotropy, chains of asymmetric vortex structures can arise in this type of films and that the vortices in the structures increase in number with the film thickness.
