1. A spin-orbit torque device comprising:
an interfacing layer comprising a spin source layer arranged to receive an electric current; and
a magnetic layer having a switchable magnetization direction,
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 for switching the switchable magnetization direction of the magnetic layer, and wherein the spin source layer comprises copper-platinum (CuPt) and the magnetic layer comprises cobalt-platinum (CoPt).
