Abstract
The effect of a surface anisotropy of the easy-plane-type on the magnetic data recording in a single-crystalline film in which walls of the domain band structure play the role of information bits has been studied by micromagnetics simulations. It is established that the surface anisotropy leads to the appearance of a domain structure with the walls of different (Neel and vortex) types. Under the action of an external field, the Neel walls can be transformed into vortex walls that can be used for magnetic data recording.
