Abstract: The magnetization reversal processes of rectangular and circular permalloy ring arrays are compared. Rectangular rings reverse via two different processes, one of which includes the formation of a vortex state. The corners of the rectangular rings affect domain wall pinning and reverse domain nucleation processes and alter the field values for the two major transitions between magnetic states as compared to a circular ring. The effects of film thickness are also investigated. Micromagnetic simulations are compared with the experiment results. © 2012 American Institute of Physics.
