Abstract:
The dynamics of domain walls in bubble films with orthorhombic anisotropy, which are known for their very high peak velocities, are examined in detail by solving the equations of motion numerically. The dependence of the peak velocity on the orientation of the domain wall with respect to the in-plane easy axis is discussed with the strength of the in-plane anisotropy as a parameter. For weakly twisted walls both parallel and perpendicular to the in-plane easy axis, an approximate expression for the nucleation threshold and the corresponding critical velocity is derived. This velocity is found to be a close approximation of the numerical results and to lie considerably below the maximum velocity of the one-dimensional theory over a large part of the range of anisotropy values examined experimentally. Measurements of the peak velocity are performed on the shrinking velocity of stripe heads. Velocities are found to increase strongly with increasing in-plane anisotropy as expected from the theoretical results, but to be generally about 10% too low.
