(a) Typical propagating spin-wave signal, which is the real part of the MSSW signal without any bias voltage. (b) Voltage-induced resonant-frequency shift of the propagating spin-waves (δf). The black (red) rectangular dots represent the frequency change of Re[S21] (Re[S12]). The black and red lines are the fitting lines for the frequency shifts δf21 and δf12, respectively. The error bars represent the standard deviation of the frequency shift obtained from the root-mean-square-error method. The inset shows the experimental (yellow solid rectangles) and fitting (green open diamond) data. The x-axis of the inset is the frequency axis, from 14.5 GHz to 16.5 GHz. All data in this figure correspond to the Fe1−xCox/Pd/MgO sample with x = 1, i.e., Fe/Co(0.3 nm)/Pd(0.2 nm)/MgO.
