A NUMERICAL INVESTIGATION OF DOMAIN-WALL OVERSHOOT IN THIN-FILMS WITH PERPENDICULAR ANISOTROPY

The dynamic structure of a magnetic domain wall in a stripe compression experiment has been investigated by numerical integration of the Landau-Lifshitz-Gilbert equation. We consider domain walls of the type found in thin film materials with a large uniaxial anisotropy perpendicular to the plane of the material. We find that a single Horizontal Bloch Line (HBL) is formed in the domain wall and is responsible for wall overshoot and saturation of the wall velocity. These results compare favorably with experimental data.
