Abstract:
1. A magnetic device comprising: a polarizing layer magnetized perpendicular to a free magnetic layer; the free magnetic layer forming a first electrode and separated from the magnetized polarizing layer by a first non-magnetic metal layer, the free magnetic layer having a magnetization vector having at least a first stable state and a second stable state; a reference layer forming a second electrode and separated from the free-magnetic layer by a second non-magnetic layer; wherein the magnetization vector is set via application of a unipolar current pulse, having either positive or negative polarity and a selected amplitude and duration, through the magnetic device bipolarly switching the magnetization vector from the first stable state to the second stable state or the second stable state to the first stable state, wherein the unipolar current pulse is orthogonal to the polarizing layer.
