Abstract:
1. A method for fabricating a CPP spin valve structure, comprising: (a) providing a substrate and depositing an oxygen doped seed layer thereon; (b) depositing an oxygen doped AFM layer on said oxygen doped seed layer; (c) depositing a synthetic anti-parallel (SyAP) pinned layer on said oxygen doped AFM layer wherein said SyAP pinned layer is a composite layer formed by sequentially depositing a non-oxygen doped pinned layer, a coupling layer, and an oxygen doped pinned layer; (d) depositing a copper spacer on the SyAP pinned layer; (e) depositing an oxygen doped free layer above the copper spacer; and (f) depositing a copper layer on the oxygen doped free layer and a capping layer on the copper layer.
