Abstract:
1. 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 field generation layer (FGL) that has an (A1/A2) (c) the non-magnetic spacer; (d) a laminated spin injection layer (SIL) with high perpendicular magnetic anisotropy (PMA) and with a (A1/A2) (e) a capping layer contacting a top surface of the SIL.
