ABSTRACT:
A soft adjacent layer (SAL) magnetoresistive (MR) sensor element and a method for fabricating the soft adjacent layer (SAL) magnetoresistive (MR) sensor element. To practice the method, there is first provided a substrate. There is then formed over the substrate a soft adjacent layer (SAL). There is then formed upon the soft adjacent layer (SAL) a dielectric layer. There is then formed at least in part contacting the dielectric layer a magnetoresistive (MR) layer, where the soft adjacent layer (SAL) and the dielectric layer are planar. The method contemplates the soft adjacent layer (SAL) magnetoresistive (MR) sensor element formed through the method.
