Abstract: Various embodiments of a magnetic stack are disclosed. In one or more embodiments, the magnetic stack includes first and second shield layers, and a magnetically responsive lamination disposed between the first and second shield layers. The magnetically responsive lamination can be configured to receive a sense current IS therethrough. The magnetic stack also includes a cooling element disposed between the first and second shield layers and thermally coupled to the magnetically responsive lamination. The cooling element can be configured to receive a bias current IB therethrough. And the cooling element can be configured to cool the magnetically responsive lamination during a read function.

Abstract: A reader sensor that has a sensor stack with an AFM layer, a pinned stabilization layer, and a pinned layer, with the pinned stabilization layer closer to the AFM layer than to the pinned layer. The stack also includes a non-magnetic spacer layer between and in contact with the pinned stabilization layer and with the pinned layer. A magnetic coupling between the pinned stabilization layer and the pinned layer is no more than 50% of a magnetic coupling between the pinned stabilization layer and the AFM layer.
