Abstract
Various embodiments of the present invention are generally directed to a magnetically responsive lamination that may be constructed with a spacer layer disposed between a first and second ferromagnetic free layer. At least one ferromagnetic free layer can have a coupling sub-layer that enhances magnetoresistance ratio (MR) of the magnetically responsive lamination.
