Patent abstract
A giant magnetoresistive spin valve sensor is provided in which first and second ferromagnetic layers comprise a Heusler alloy. A non-ferromagnetic spacer layer is positioned between the first and second ferromagnetic layers. The non-magnetic spacer layer has an energy band which is similar to the energy bands of the Heusler alloy of the first and second ferromagnetic layers to allow a giant magnetoresistive effect to occur.
