    摘要： The disclosure is related to oscillators and more specifically voltage controlled oscillators. Magnetic voltage controlled oscillators are presented that comprise current-biased magnetic thin film structures that can exhibit microwave oscillations and are tunable with current as well as magnetic field. In a particular embodiment, an array of oscillators, which may be activated with a current while in a magnetic field, can be positioned adjacent a spin valve layer to produce a spinwave disturbance in the spin valve layer. An array of detectors that can sense periodic motion of the magnetization of the spin valve layer may also be positioned adjacent the spin valve layer. The detectors may produce an oscillating output signal from the detected periodic motion.
