(color online) (a) The DC-voltage spectra of a YIG(16 nm)/Pt(10 nm) strip at various angle θ. The symmetrical (b) and asymmetrical (c) components of DC-voltages defined in Eq. (1) were extracted. The solid lines are the best fits of Eq. (2) with . The inset illustrates experimental setup and angle θ.
