Abstract:

We proposed a novel regime of operation of a spin-torque diode, based on excitation of large-angle out-of-plane magnetization precession. The specific features of the proposed spin-torque diode are Higher output voltage 1 mV. The out-of-plane precession regime might be responsible for extremely high diode efficiencies observed in recent experiments. CPW antenna was used as a feed line to the detector. The transmitting antenna was a commercial horn antenna. Ten spintronic detectors of microwave radiation were built and tested at TARDEC. We are in the process of integrating of these radar detectors into armor. There will be more tests performed at TARDEC when integration is completed. Arrays of spintronic detectors have two important applications analysis of frequencies of incoming signals and RF energy harvesting.
