Abstract
A method and system for providing a magnetoresistive sensor is disclosed. The method and system include providing a first pinned layer, providing a free layer having a length, and providing a first spacer layer disposed between the first pinned layer and the free layer. The first spacer layer has a first interface with the first pinned layer. The method and system also include providing a second pinned layer and providing a second spacer layer disposed between the free layer and the second pinned layer. The second spacer layer has a second interface with the second pinned layer. A direction of a current passed through the magnetoresistive sensor is through the first interface, through the second interface, and along at least a portion of the length of the free layer.
