A carrier-mediated magnetic phase change spin transistor is disclosed. In general, the spin transistor includes a Dilute Magnetic Semiconductor (DMS) channel and a gate stack formed on the DMS channel. The gate stack includes a multiferroic gate dielectric on the DMS channel, and a gate contact on a surface of the multiferroic gate dielectric opposite the DMS channel. The multiferroic gate dielectric is formed of a multiferroic material that exhibits a cross-coupling between magnetic and electric orders (i.e., magnetoelectric coupling), which in one embodiment is BiFeO3 (BFO). As a result, the multiferroic material layer enables an electrically modulated magnetic exchange bias that enhances paramagnetic to ferromagnetic switching of the DMS channel. The DMS channel is formed of a DMS material, which in one embodiment is Manganese Germanium (MnGe). In one embodiment, the DMS channel is a nanoscale DMS channel.
