Abstract:
A magnetic device and method for providing the magnetic device are described. The magnetic device includes magnetic junctions and spin-orbit interaction (SO) active layer(s). Each magnetic junction includes free and pinned layers separated by a nonmagnetic spacer layer. The pinned layer has a perpendicular magnetic anisotropy (PMA) energy greater than an out-of-plane demagnetization energy. The pinned layer includes a magnetic barrier layer between a magnetic layer and a high PMA layer including at least one nonmagnetic component. The magnetic barrier layer includes Co and at least one of Ta, W and Mo. The magnetic barrier layer is for blocking diffusion of the nonmagnetic component. The SO active layer(s) are adjacent to the free layer. The SO active layer(s) carry a current in-plane and exert a SO torque on the free layer due to the current. The free layer is switchable between stable magnetic states using the SO torque.

Claim (Index 1):
A magnetic device comprising:\n a plurality of magnetic junctions, each of the plurality of magnetic junctions including a free layer, a pinned layer and a nonmagnetic spacer layer, the nonmagnetic spacer layer being between the pinned layer and the free layer, the pinned layer having a pinned layer perpendicular magnetic anisotropy energy greater than a pinned layer out-of-plane demagnetization energy, the pinned layer including a high perpendicular magnetic anisotropy (PMA) layer including at least one nonmagnetic component, a magnetic layer and a magnetic barrier layer between the high PMA layer and the magnetic layer, the magnetic barrier layer including Co and at least one of Ta, W and Mo, the magnetic barrier layer being a barrier to diffusion of the nonmagnetic component of the high PMA layer; and at least one spin-orbit interaction (SO) active layer adjacent to the free layer of the each of the plurality of magnetic junctions, the at least one SO active layer carrying a current in-plane, the at least one SO active layer exerting a SO torque on the free layer due to the current passing through the at least one SO active layer, the free layer being switchable between a plurality of stable magnetic states using the SO torque.
