Abstract

A three-dimensional micromagnetic computer simulation of transition structures that separate regions of C- and S-shaped vortex asymmetric domain walls in films with easy magnetization axes parallel to the surface has been performed. Films with uniaxial and triaxial magnetic anisotropy (with the surface parallel to crystallographic plane (100)) have been examined. New types of transition structures (including those containing Bloch points) have been obtained.
