A magnetoelectronic thin-film transistor is proposed that can display negative differential resistance and gain. The working principle is the modulation of the soure–drain current in a spin valve by the magnetization of a third electrode, which is rotated by the spin-torque created by a control spin valve. The device can operate at room temperature, but in order to be useful, ferromagnetic materials with polarizations close to unity are required. © 2003 American Institute of Physics.
