Abstract
According to one embodiment, a magnetic head includes a barrier layer having a crystalline structure, a first magnetic layer above the barrier layer, a magnetic insertion layer above the first magnetic layer, and a second magnetic layer above the magnetic insertion layer, the second magnetic layer having a textured face-centered cubic (fcc) structure. The first magnetic layer comprises a high spin polarization magnetic material having a crystalline structure and a characteristic of crystallization being more similar to the crystalline structure of the barrier layer than a crystalline structure of the second magnetic layer and the magnetic insertion layer comprises a magnetic material having a crystalline structure and a characteristic of crystallization being more similar to the crystalline structure of the second magnetic layer than the crystalline structure of the barrier layer. Additional magnetic head structures and methods of producing magnetic heads are described according to more embodiments.
