摘要
Methods, systems, and devices are disclosed for enhancement of spin-orbit torque. In one aspect, a magnetic device includes a magnetic tunneling junction (MTJ), including a free magnetic layer, a pinned magnetic layer and a non-magnetic junction layer between the free magnetic layer and the pinned magnetic layer, and a spin Hall effect metal layer that includes one or more insertion metal layers operable to introduce interfacial scattering of electrons flowing in the spin Hall metal layer to increase the spin current that interacts with and changes the magnetization of the free magnetic layer of the MTJ.
