Spin separation in cyclotron motion

A method aimed at the spatially separation of spin currents in materials with intrinsic spin orbit interactions by a weak magnetic field was presented. The method was achieved in semiclassical cyclotron motion, where distinct spins were characterized by distinct cyclotron radii and frequencies. It was shown that the cyclotron motion can separate the particles with different masses as well as particles with different spin-orbit parameters. The spatial separation of spins were also demonstrated experimentally by selectively detecting spin-polarized currents.
