ABSTRACT:
The present invention provides techniques for data storage. In one aspect of the invention, a semiconductor device is provided. The semiconductor device comprises at least one free layer and at least one fixed layer, with at least one barrier layer therebetween. At least one pinned magnetic layer is separated from the at least one free layer by at least one non-magnetic layer, the at least one pinned magnetic layer and non-magnetic layer being configured to cancel out at least a portion of a Neel coupling between the at least one free layer and the at least one fixed layer.
