Pinned layer structure for a spin valve sensor having cobalt iron (CoFe) and cobalt iron oxide (CoFeO) laminated layers

摘要

A pinned layer structure of a spin valve sensor includes a laminate of alternating layers of cobalt iron (CoFe) and cobalt iron oxide (CoFeO). A range of thicknesses of each cobalt iron oxide (CoFeO) layer is from 5-20 Å. A first one of the cobalt iron (CoFe) layers interfaces a pinning layer in the spin valve sensor and a second one of the cobalt iron (CoFe) layers interfaces a spacer layer in the spin valve sensor.
