Simulation of skew domain wall bowing in SiFe laminations with asymmetric roll orientation

Cyclic motion of 180° domain walls spanning perfect monocrystalline laminations with first-order positive cubic anisotropy (like 3% SiFe) has been simulated using a finite segment technique. Only drive field, eddy field, and surface tension forces on the domain wall were considered. Calculations were made for various crystal orientations over the range between (110) [001]. At intermediate orientations the profile of a rapidly moving domain wall suffers shearing and bowing distortion; this is very different from the symmetric bowing reported in earlier work on the symmetric
