Working with spin pumping and spin-torque ferromagnetic resonance measurements, we investigate the spin-charge conversion in epitaxial Bi($\sqrt{3}$ $\times \sqrt{3}$) $R30°$/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 Sánchez 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.

Bi( 3 ×3 ) R30° /Ag(111) 结构中的自旋电荷转换

使用自旋泵浦和自旋扭矩铁磁共振测量，我们研究了外延 Bi（$\sqrt{3}$ $\times \sqrt{3}$) $\mathrm{电阻}30°$/Ag(111) 结构通过分子束外延生长。结果表明，我们的 Bi/Ag 结构中自旋电荷转换的符号与 Sánchez 等人的相反。(2013)，表明我们的 Bi/Ag 结构中的自旋电荷转换由（逆）自旋霍尔效应主导，而不是（逆）Rashba-Edelstein 效应。
