1. A method of forming a spin valve sensor, comprising:

  • forming a first pinned layer having a first magnetic orientation on a substrate, the method of forming the first pinned layer includes embedding an inner ferromagnetic layer between first and second ferromagnetic layers, wherein the inner layer provides a greater positive magnetostrictive coefficient in relation to the first and second ferromagnetic layers; and

    depositing a second pinned layer having a second magnetic orientation above the first pinned layer, wherein the first and second magnetic orientations are self-biased anti-parallel in relation to one another.
