Theoretical calculation for a simple nanoscale magnetoelectronic device to function as a microwave generator based on the spin-transfer torque effect is presented. The device is unique because the output amplitude and frequency can be continuously tuned by the electrical current in the microwave frequency range. Analysis and discussion of the device structure, function, and realization are provided. © 2004 American Institute of Physics.
