The magnetic behavior of three-layer Co/Al2O3/Co samples obtained by the magnetron sputtering method with variable thickness of the oxide layer from 3 to 8 nm and constant thicknesses of the magnetic cobalt layers of 10 nm has been studied. Contributions to the magnetic behavior from the upper oxidized surface of cobalt (Co-CoO interface), interlayer interaction of cobalt layers and effects due to defects at the Co/Al2O3 and Al2O3/Co interfaces have been analyzed. A negative exchange bias was detected at low temperatures. The temperature at which a step-like hysteresis loop appeared increased with increasing oxide layer thickness Keywords: interface, ferromagnet, oxide layer, interlayer interaction, exchange bias.
