Highly stable vortex state in sub-100 nm nanomagnets

We report on the magnetization reversal process in sub-100 nm Ni80Fe20 asymmetric ring. The switching mechanism involves a stable vortex state due to the strong anisotropy imposed on the narrow arm of the ring. Experimental demonstration shows that such vortex configuration does not annihilate until...
