Abstract

A magnetic junction and method and programming the magnetic junction are described. The magnetic junction has a free layer, a reference layer, and a nonmagnetic spacer layer between reference and free layers. The free layer is switchable between stable magnetic states when a write current is passed through the magnetic junction. The free layer has a perpendicular magnetic anisotropy exceeding its out-of-plane demagnetization energy a quiescent state. The free layer has a magnetostriction such that the perpendicular magnetic anisotropy changes in the presence of a programming voltage applied for the magnetic junction, canting that the magnetic moment by at least five degrees from its quiescent direction. The programming voltage is at least 0.1 volt and not more than 2 volts. The nonmagnetic spacer layer is an insulating tunneling barrier layer and/or the magnetic junction includes an additional insulating layer adjacent to the opposite interface of the free layer.
