Abstract

Using three-dimensional micromagnetic simulation, we studied dynamic processes in a domain wall moving under the action of the dc magnetic field in a magnetically soft film with an in-plane uniaxial anisotropy. The features of the dynamics are investigated depending on the film thickness. Visualization methods based on the calculation of topological invariants were used.
