Patent ID: 8184411

Claim:
A spin valve structure in a spintronic device, comprising: (a) a composite seed layer comprising at least a lower Ta layer formed on a substrate and a metal (M1) layer having a fcc(111) or hcp(001) crystal structure disposed on the lower Ta layer; (b) a free layer and a reference layer wherein one or both of said free layer and reference layer are comprised of a laminated structure with a plurality of (CoFe/Ni), (CoFeR/Ni), (Co/NiFe), (Co/NiCo), (CoFe/NiFe), or (CoFe/NiCo) stacks of layers in which a CoFe, CoFeR, or Co layer has a lesser thickness than a Ni, NiFe, or NiCo layer; (c) a non-magnetic layer formed between the reference layer and the free layer; (d) an interfacial layer formed between the non-magnetic layer and each of the laminated free layer and/or laminated reference layer; and (e) a cap layer.
