ABSTRACT:
An embodiment of the invention is a transistor formed in part by a ferromagnetic semiconductor with a sufficiently high ferromagnetic transition temperature to coherently amplify spin polarization of a current. For example, an injected non-polarized control current creates ferromagnetic conditions within the transistor base, enabling a small spin-polarized signal current to generate spontaneous magnetization of a larger output current.
