The magnetization switching in Permalloy square rings was studied using diffraction magneto-optic Kerr effect combined with numerical micromagnetic simulations. A two-step switching process was shown as the external field was swept along both the ring edge and the diagonal. Results showed that in order to reproduce the observed two-step reversal, slight asymmetry has to be introduced into the ring shape.

Abstract

The magnetization switching in Permalloy square rings was studied using diffraction magneto-optic Kerr effect combined with numerical micromagnetic simulations. A two-step switching process was shown as the external field was swept along both the ring edge and the diagonal. Results showed that in order to reproduce the observed two-step reversal, slight asymmetry has to be introduced into the ring shape.
