Exchange bias between ZnCoO and IrMn

In this work, we investigate the exchange bias between DMS ZnCoO and IrMn. Epitaxial ZnCoO thin films were fabricated by using ion beam deposition (IBD). ZnCo
_0.07
O films exhibited room-temperature ferromagnetic behavior and a large exchange bias field between ZnCo
_0.07
O and IrMn was observed at 5K.
