Classification: CPC H | IPC H

Claim 7:
8. A spin-orbit torque device comprising:
an interfacing layer comprising a substrate layer; and
a magnetic layer having a switchable magnetization direction and is arranged to receive an electric current, the magnetic layer comprises a functionally graded magnetic layer having a composition gradient adapted to create a broken inversion symmetry to interact with the electric current to generate a damping-like torque in the magnetic layer,
wherein an interface is formed between the interfacing layer and the magnetic layer, the interface having a 3m1 crystallographic point group symmetry adapted to interact with the electric current to generate a spin torque in a presence of the damping-like torque for switching the magnetization direction of the magnetic layer.
