摘要
The present study shows that the often observed and undesirable coercivity enhancement in the free Co layer of spin valves result from magnetostatic coupling between domain walls in the free Co layer and high coercivity NiO-pinned Co layer. The observed escape fields, in excess of intrinsic coercivity of Co single film, required to overcome magnetostatic coupling between domain walls are in agreement with theoretically predicted values.
