In certain embodiments, an apparatus includes a top shield, bottom shield, polarizer, nonmagnetic conductor layer, and a sensor stack having a first sensor layer. The sensor stack is positioned at a distance recessed from a first plane. The nonmagnetic conductor layer is positioned between the polarizer and the first sensor layer. A magnetization of the first sensor layer is arranged and configured to move in the same direction as a magnetization of the polarizer.
