Abstract
In a simple spin valve device, electrical current parallel to the layers generates magnetic fields in opposite directions in the free and reference (or pinned) layers. We exploit this to distinguish between the free layer and the pinned layer as the location of common two-state magnetic instabilities. In addition, we demonstrate a method for determining both the direction and magnitude of the difference in magnetization between the two states by varying applied field direction
