We propose a method for simultaneous enhancement of the Radio Frequency (RF) detection sensitivity and the detection frequency of a Magnetic Tunnel Junction (MTJ) by utilizing voltage controlled magnetic anisotropy (VCMA) and the technique of parametric synchronization. We show that the presence of VCMA enhances the coupling strength of parametric synchronization by ∼40 times, giving a very high sensitivity of the order of 105 mV/mW. We discuss the detailed field, bias, external RF power, and temperature dependence of the phenomenon for optimization of MTJ based detectors. The results will be useful for realizing highly sensitive RF detectors with high detection frequency working at low input powers.We propose a method for simultaneous enhancement of the Radio Frequency (RF) detection sensitivity and the detection frequency of a Magnetic Tunnel Junction (MTJ) by utilizing voltage controlled magnetic anisotropy (VCMA) and the technique of parametric synchronization.
