Dynamics of Domain Boundary with the Complex Internal Structure of the Cylindrical Magnetic Domain in External Magnetic Fields

Abstract

The dynamical behaviour of the domain wall with complex interior structure of the cylindrical magnetic domain formed in a uniaxial magnetic film is investigated. The opportunity of generation of vertical Bloch lines by the external alternating magnetic field is shown. Conditions of a given process realization are determined. As shown, a presence of the Bloch point within the domain wall inhibits the Bloch lines’ generation.
