Magnetoresistive stack/structure and methods therefor

Abstract:

A magnetoresistive device with a magnetically fixed region having at least two ferromagnetic regions coupled together by an antiferromagnetic coupling region. At least one of the two ferromagnetic regions includes multiple alternating metal layers and magnetic layers and one or more interfacial layers. Wherein, each metal layer includes at least one of platinum, palladium, nickel, or gold, and the interfacial layers include at least one of an oxide, iron, or an alloy including cobalt and iron.
