The structural and magnetic properties of o-HMO/SRO heterostructures are measured. The magnetic hysteresis loops of o-HMO/SRO show exchange bias at temperatures below the antiferromagnetic transition temperature of o-HMO. Furthermore, the large exchange bias field up to 815 Oe is observed at 5 K. These results demonstrate that the exchange bias between a FM oxide and the multiferroic o-HMO could be useful for future applications on spintronic devices.journal article10.1063/1.4801504
