Abstract
Described is a spin torque device, and a spintronics device Incorporating the spin torque device. The spin torque device comprises a magnetic layer having a switchable magnetisation direction along a first axis, and a spin source layer adapted to generate a spin current from a current Injected along a second axis perpendicular to the first axis. Electrons of different spins in the spin source layer are rearranged by scattering so the spin current is generated in a plane perpendicular to the second axis and polarized at an angle to the first axis, so that the spin current diffuses into the magnetic layer to produce spin torque to switch the magnetisation direction.
