The ability to manipulate spin of charge carries in a controllable fashion is central to the rapidly developing field of spintronics, as well as for the development of spin-based devices for quantum information processing. Electrical injection of spin-polarized currents is proven to be a formidable challenge. We realized a solid-state analog of the famous Stern-Gerlach experiment in atomic physics, with spin-orbit interactions playing the role of the gradient of magnetic field. We achieved spatial separation of spins and bipolar spin filtering using cyclotron motion in a weak magnetic field.
