Dynamics of domain walls at high drives with boundary conditions asymmetric due to magnetic moment pinning

Numerical solutions of the equations of motion of a flat, thin domain wall are solved with asymmetric boundary conditions. Absolute inhibition of the precession of magnetic moments is assumed at one film surface while force-free boundary conditions are assumed at the other film surface. The numerical calculations are shown to give good agreement with high speed photography data on the velocity of bubbles in radial expansion in double layer self-biasing films. A form of stationary motion at high drives is found.
