Abstract: We present a systematic study of the magnetic properties of exchange biased Co (25 nm) /CoO (tCoO) /Cu (2 nm) elongated nanoring arrays. The reversal mechanism in the exchange biased nanorings is directly compared to that of unbiased nanorings of identical geometry at varying temperatures. We observe that along the field cooling direction, the exchange biased nanorings exhibit reversal via shifted vortex states with enhanced magnitudes of onion→vortex and vortex→reverse onion transition fields. The magnitude of exchange bias field is also found to be strongly dependent on the CoO layer thickness tCoO, and decreases monotonically with increasing tCoO. Due to the interplay between the exchange and Zeeman energies, the exchange bias field could also be varied by adjusting the field cooling strength. © 2009 American Institute of Physics.
