(Color online) Experiment setup of electrical detection of NLFMR based on MTJ.
(Color online) (a) Typical microwave induced voltage spectra measured at 2.6 GHz with different microwave powers. (b) Corresponding two-dimensional mapping as a function of the microwave power and the applied static magnetic field. The positions of maximum voltage points at a certain power are labeled by the black crosses.
(Color online) Maximum values (empty circles) calculated from the maximum voltage points extracted from Fig. 2(b) as a function of the square root of the microwave power. The solid lines are the fitting curves by theory models. The inset shows the enlarged part of lower power region but is plotted as a function of power.
