(a) Ag thickness dependence of the sheet resistance RS of NiFe/Ag(t)/Bi samples, and a linear fit yielding ρAg=8.3 μΩ cm−1, (b) Ag thickness dependence of the charge current, for one of the NiFe/Ag(t)/Bi sample series (the length l and width a of the samples are, respectively, 2.4 mm and 0.4 mm, the current is normalized for hrf =1 G), (c) as in (b) but for all the series (l=1, 1.5, 2.4 and 3 mm) and (d) for all the series, variation of the ratio λIREE of the horizontal charge current density, jC=IC/a (derived from the DC voltage by Equation 2), to the vertical spin current density jS injected by spin pumping. As jC is in A m−1 and jS in A m−2, λIREE is a length expressed in nm on the figure.
