ABSTRACT:
A coupled ferromagnetic structure includes a first ferromagnetic layer, a spacer layer on a first surface of the first ferromagnetic layer, and a second ferromagnetic layer on the spacer layer. Interlayer exchange coupling occurs between the first and second ferromagnetic layers. The coupling may be ferromagnetic or antiferromagnetic. Morphology of the first surface is modified to tailor the interlayer exchange coupling. The structure may form a part of a magnetoresistive device such as a magnetic tunnel junction.
