Unipolar devices constructed from ferromagnetic semiconducting materials withvariable magnetization direction are shown theoretically to behave verysimilarly to nonmagnetic bipolar devices such as the p-n diode and the bipolar(junction) transistor. Such devices may be applicable for magnetic sensing,nonvolatile memory, and reprogrammable logic.
