Abstract:
A soft adjacent layer (SAL) magnetoresistive (MR) sensor element comprising:a substrate; a dielectric layer formed over the substrate, the dielectric layer having a first surface of the dielectric layer and a second surface of the dielectric layer opposite the first surface of the dielectric layer; a magnetoresistive (MR) layer formed over the substrate, the magnetoresistive (MR) layer contacting the first surface of the dielectric layer; a soft adjacent layer (SAL) formed over the substrate, the soft adjacent layer (SAL) having a first surface of the soft adjacent layer (SAL) and a second surface of the soft adjacent layer (SAL) opposite the first surface of the soft adjacent layer (SAL), the first surface of the soft adjacent layer (SAL) contacting the second surface of the dielectric layer; and a transverse magnetic biasing layer formed over the substrate, the transverse magnetic biasing layer contacting the second surface of the soft adjacent layer (SAL), where the magnetoresistive (MR) layer is formed interposed between the substrate and the soft adjacent layer (SAL).
