Schematic of the microwave amplification (left) and magnetic field dependence of the microwave power reflectivity spectra (right). The reflected microwave is amplified by the dc voltage (Vdc) biased MTJ. In our experiment, we have obtained a microwave power reflectivity of more than 1.6 under an external magnetic field of 50 mT and frequency of 0.4 GHz.
