Abstract

Conditions are found for the surface anisotropy to have considerable effect on the two-dimensional distribution of magnetization in domain walls in thin magnetic films with a positive uniaxial of magnetic anisotropy parallel to the surface. Three ranges of the surface anisotropy constant Ka are found with different series of wall transformations depending on the film thickness. Possible structures in that series are the vortexless Bloch wall (BW), double vortexed BW, single vortex BW, and the Neel wall
