Fig. 5: Vertical spin pumping in FeRh/Py/Al.
From: Spin pumping during the antiferromagnetic–ferromagnetic phase transition of iron–rhodium
a Pure spin pumping voltages acquired at φH = 0° and 180° at 22 GHz and 300 K, when FeRh is in AFM state. b Pure spin pumping voltages acquired at 400 K, when FeRh is in FM state. Mutual spin pumping from Py into FeRh (FMR of Py), or from FM-FeRh into Py (FMR of FeRh), is observed. c Temperature dependence of ISHE voltages measured at the FMR of Py. The error bars are smaller than the size of the symbols. d Temperature dependence of spin-to-charge conversion efficiency of FeRh, which shows a larger spin-to-charge conversion efficiency at the AFM phase, indicating that AFM-FeRh can be a good spin sink. The errors bars in c and d are standard deviations obtained from the fit.
