We show that the rotation of a magnetic domain wall (DW) can be induced by the injection of a dc current into a magnetic wire with a DW. A novel three-terminal device that produces microwaves by utilizing the current-induced DW rotation is proposed. The frequency of the microwaves can be tuned by adjusting the current density through the wire, and the amplitude of the microwaves can be regulated through a dc bias applied to the magnetic tunnel junction.
