Abstract: We have investigated the giant magnetoresistance (GMR) responses of the pseudospin valve elliptical rings in close proximity with individual magnetic elements. Significant modifications of the GMR responses were observed due to the effects of magnetostatic coupling between the rings and the magnetic elements. We observed that the vortex state stability is significantly sensitive to the position, orientation of the magnetic elements, and the direction of the applied field. We also investigated the switching field reproducibility of the rings for onion→vortex and vortex→onion transitions and observed that the ring with asymmetrically placed magnetic elements shows the most reproducible switching states. © 2009 American Institute of Physics.
