Interaction between a Bloch domain wall and a pinning plane

A numerical simulation of the interaction between a Bloch domain wall and an one-dimensional anisotropy modulation has been done. Different pinning planes were simulated with several anisotropy modulations. The results show the velocity, shape and domain wall energy as a function of the distance between the wall and the pinning plane. The magnetic fields necessary to overcome the different pinning planes have been obtained.
