Abstract
A thermally stable spin valve sensor having an increased GMR ratio by virtue of an AP pinned layer structure in which the first and second pinned layers are separated by an AP coupling layer having a nano-oxide layer formed as an oxidized surface portion of the AP coupling layer. The nano-oxide layer provides an increase in the specular scattering, and in turn, an increase in the GMR ratio.
