Switching in Assymmetric Permalloy Nanorings

Caption

A magnetic field pulse switches the initial vortex state to "onion state" with two walls. In the subsequent magnetic snapshots the domain wall motion is shown. After 58 ns both walls meet and annihilate, thus completing the switching process into the opposite sense of rotation.
