Extended Data Fig. 3: Dependence of resistance change and inverse spin Hall voltage on the current polarity.
From: Signatures of longitudinal spin pumping in a magnetic phase transition
a, VOSC profile for positive (black) and negative (green) magnetic fields when positive current is injected. It is important to note that distinguishing the difference in VOSC between positive and negative fields is challenging from VOSC versus time plot, as explained in Supplementary Note S3. b, Resistance variation obtained from the VOSC profile. c, Subtracted signal \({V}_{{odd}}=\{{V}_{{OSC}}(+H)-{V}_{{OSC}}(-H)\}/2\). The gray line indicates the time when the phase transition occurs. d-f, same as a-c obtained for a negative current. The results are obtained from FeRh (170 nm)/Pt (5 nm).
