Abstract
A hysteresis loop shifted relative to the zero field in a fragment of a 100-nm-thick film with inplane anisotropy has been calculated based on a three-dimensional micromagnetic simulation. The reason for the revealed effect is an asymmetric pinning of a vortex domain wall by regions with enhanced values of the saturation magnetization and anisotropy constant.
