Abstract
A spin-orbit torque magnetic random-access memory (SOT-MRAM) device includes a substrate, a spin orbit torque line above the substrate, a composite-metal-oxide seed layer above the spin orbit torque line, and a magnetic tunnel junction above the composite-metal-oxide seed layer. The magnetic tunnel junction includes a free layer above the composite-metal-oxide seed layer, a main tunneling barrier layer above the free layer, and a pinned layer above the main tunneling barrier layer.
