Аннотация

We studied cobalt films deposited by the magnetron method on an amorphous Al2O3 layer. The morphological and magnetic features associated with the formation of a naturally oxidized antiferromagnetic film on cobalt and the Al2O3/Co interface were studied. A change in the sign of the exchange bias at temperatures below 200 K was detected when the thickness of the cobalt layer on the Al2O3 film increased to more than 10 nm.
