a \({V}_{2\omega }\) vs. angle θ between the external B field and the direction perpendicular to respective Pt electrodes for Device-S and Device-W. The solid lines are fits to a cosine function. Both magnon valves have the same channel length of 750 nm and are excited with \({I}_{{in}}=60\mu A\). b \({V}_{2\omega }\) vs. T at θ = 0 (\({V}_{2\omega,0}\) vs. T). c Magnetic field dependence of \({V}_{2\omega,0}\). d \({V}_{2\omega,0}\) vs. the square of the injection current \({I}_{{in}}^{2}\). Here, experimental data and fitting curves for Device-S (Device-W) are in red (blue), respectively.
