ABSTRACT:
A method and apparatus for using a specular scattering layer in a free layer of a magnetic sensor while stabilizing the free layer by direct coupling with an antiferromagnetic layer is disclosed. A specular scattering layer is formed in a free layer of a magnetic sensor while stabilizing the free layer by direct coupling with an antiferromagnetic layer. An antiferromagnetic layer is formed abutting the free layer to provide direct exchange coupling with the free layer. The specular layer in the free layer removes any ΔR degradation caused by placement of an antiferromagnetic layer over the free layer.
