Spin Seebeck effect-driven spin galvanic effect measurements. a Experimental configuration for the SSE-driven SGE measurements. b Voltages measured in the two different configurations for the test sample (seed/PML/Cu/Py/Pt) and control sample (seed/PML/Cu/TaO x /Py/Pt). V even and V odd are the sum and difference of the two voltage curves when \(\hat {\bf{m}}\) is polarized up and down, respectively. c Angle dependence of the voltage signals associated with Py switching. Here \(\Delta V_{{\rm{Py}}}^{{\rm{even}}}\) is the first term of V even in Eq. (9) and \(\Delta V_{{\rm{Py}}}^{{\rm{odd}}}\) is the first term of V odd in Eq. (9). The red curves are fits to \(\Delta V_{{\rm{Py}}}^{{\rm{even}}} = 21.7\,{\rm{cos}}\left( {\frac{\pi }{{180}}\phi } \right)\) and \(\Delta V_{{\rm{Py}}}^{{\rm{odd}}} = 0.61\,{\rm{sin}}\left( {\frac{\pi }{{180}}\phi } \right)\). The error bars represent the standard deviation calculated from the linear fitting in b used to calculate \(\Delta V_{{\rm{Py}}}^{{\rm{even}}}\) and \(\Delta V_{{\rm{Py}}}^{{\rm{odd}}}\)
