Abstract:
1. A method of forming a hard bias structure for providing longitudinal biasing to a free layer in an adjacent spin valve element; comprising: (a) providing a spin valve element with a plurality of layers including a free layer formed therein, and having a top surface and sidewalls, and formed on a substrate; (b) forming an isolation layer made of a metal oxide, metal nitride, or metal oxynitride with a first section on said substrate and a second section along the sidewalls of the spin valve element; (c) depositing a composite seed layer having a fcc(111) crystalline lattice structure on the first and second sections of said isolation layer, said composite seed layer comprises at least a lower Ta layer and a metal M1 layer having a fcc(111) or hcp(001) crystal orientation disposed on the lower Ta layer; (d) forming a (R1/R2) (e) forming a capping layer on said (R1/R2)
