Abstract

See full text

A magnetic device comprising having a first magnetic layer having a first magnetization direction, a second magnetic layer having a second magnetization direction, a first coupling layer interposed between the first and second magnetic layers, a third magnetic layer having a third magnetization direction, a first magnetoresistive layer interposed between the third magnetic layer and the second magnetic layer, and a circuit connected to one or more of the layers of the magnetic device by at least a pair of leads. The circuit is configured to determine a change in resistance between the pair of leads. The change in resistance is based at least in part on a change in an angular relationship between the third magnetization direction and the second magnetization direction caused by an external magnetic field or a current passing through at least a portion of the device.
