There has been widespread interest in the development of semiconductor spintronic devices for information processing and storage. While much of the research has been centered on the Datta-Das spin field effect transistor, it has not been realized. As an alternative approach, the bipolar magnetic junction transistor (MJT) has been proposed. Recently the bipolar MJT has been demonstrated using the dilute magnetic semiconductor InMnAs. The transistor operates at room temperature with a gain of the order of 20. Logic circuits have been proposed based on both magnetic semiconductor diodes and MJT devices.
