Influence of the antidot structure of the CoO layer in the CoO/Co/Cu/NiFe film on the magnetization process in each individual layer was studied by measuring the magnetoresistance. Resistance changes corresponding to the magnetization reversal of the Co layer in the antidot region were observed in addition to the main changes corresponding to that of the Co layer covered by the CoO. This suggests that the domain structure of the Co layer can be controlled by the patterned CoO. It was found that the domain walls nucleated in the antidot region enhance the coercivity of the Co layer and cause the loop shift in the NiFe layer, whose direction is parallel to the exchange bias from the CoO, via the interlayer coupling.
