摘要：
Working with spin pumping and spin-torque ferromagnetic resonance measurements, we investigate the spin-VV charge conversion in epitaxial Bi(3 x 3) R30 degrees/Ag(111) structure grown by molecular beam epitaxy. The results show that the sign of the spin-charge conversion in our Bi/Ag structure is opposite to that in Sanchez et al. (2013), indicating the spin-charge conversion in our Bi/Ag structure is dominated by the (inverse) spin Hall effect rather than the (inverse) Rashba-Edelstein effect.
