Abstract:
A method and system for providing a magnetic read transducer is described. The magnetic read transducer includes a magnetoresistive sensor a shield, and a spin pumping barrier layer. The magnetoresistive sensor includes a pinned layer, a spacer layer, and a free layer. The spacer layer is nonmagnetic and resides between the pinned layer and the free layer. The free layer is between the pinned layer and the shield. The spin pumping barrier layer is between the shield and the free layer.
