Patent ID: 8488373

Claim:
A spin transfer oscillator (STO) 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 contacting the lower Ta layer; (b) a laminated spin injection layer (SIL) with substantial perpendicular magnetic anisotropy (PMA) contacting a top surface of the seed layer; (c) an interfacial layer comprised of Fe (100-V) Co v where v is from 5 to 100 atomic % that contacts a top surface of the laminated SIL; (d) a non-magnetic spacer that contacts a top surface of the interfacial layer; (e) a field generation layer (FGL) formed on the non-magnetic spacer; and (f) a capping layer contacting a top surface of the FGL.
