We propose to develop a prototype of a novel spintronic spectrum analyzer using an array of nano-scale magnetic spin-torque detectors. The operation of the proposed spectrum analyzer is based on the recently discovered effects of spin-transfer torque and spin-diode effects in nano-scale magnetic multilayered elements, the fabrication of which became possible due to the recent advances in nano-fabrication techniques. We propose two architectures of spintronic spectrum analyzers based either on the regular arrays of discrete magnetic tunnel junction (MTJ) nano-pillars, or on randomized arrays of spin torque detectors coupled to the same spin wave waveguide. The experimental prototype spectrum analyzer comprised of a pair of magnetic tunnel junction (MTJ) nano-pillars developed during the Phase I of this Research Program have demonstrated the spectrum analysis in the frequency interval from 4.9 to 5.6 GHz with the accuracy of 50 MHz. During the Phase II we are planning to increase the number of MTJ nano-pillars to 10 to achieve the frequency bandwidth of the analysis of the order of 10 GHz, detection time less than 200 ns, and frequency resolution of 30 MHz or better. We will also study theoretically randomized arrays of spin torque detectors.
