MAGNETIC DEVICES INCLUDING MAGNETIC JUNCTIONS HAVING TILTED EASY AXES AND ENHANCED DAMPING PROGRAMMABLE USING SPIN ORBIT TORQUE
Abstract:
A magnetic memory including a plurality of magnetic junctions and at least one spin-orbit interaction (SO) active layer is described. Each of the magnetic junctions includes a pinned layer, a free layer and a nonmagnetic spacer layer between reference and free layers. The free layer has at least one of a tilted easy axis and a high damping constant. The tilted easy axis is at a nonzero acute angle from a direction perpendicular-to-plane. The high damping constant is at least 0.02. The at least one SO active layer is adjacent to the free layer and carries a current in-plane. The at least one SO active layer exerts a SO torque on the free layer due to the current. The free layer is switchable using the SO torque.
