Abstract

The influence of magnetostatic interactions on a wire domain structure is investigated here using the simplest possible situation: a) the wire has perfect cylindrical shape, b) the magnetic anisotropy is uniaxial with the easy anisotropy axis parallel to the wire axis, c) the material parameters of the wire correspond to a soft magnetic case, M_s ²GtK₁, where M_s is the saturation magnetization and K₁ is the anisotropy constant. Axial and circular magnetization processes are studied in detail and the influence of surface defects on the domain wall mobility is considered.
