Abstract
The asymmetric pinning of a vortex-domain wall in regions with enhanced values of saturation magnetization and the anisotropy constant (defects) has been studied by a three-dimensional micromagnetic simulation at different geometric parameters of these regions. The dependences of the geometry of shifted hysteresis loops on a spacing between two defects and their size in a 100-nm-wide uniaxial magnetic film have been obtained.
