我们研究了具有 Cu/Bi2O3 或 Ag/Bi2O3 Rashba 界面的磁性异质结构在面外磁场下的横向响应。我们检测到 Cu/Bi2O3 和 Ag/Bi2O3 界面在横向电阻上有相反贡献，这与两个界面自旋/电荷相互转换的相反符号有趣地吻合。我们推测对横向电阻的相反影响表明发生了转换自旋电流的自旋交换。由于 Cu 和 Ag 层中的自旋交换出现了横向自旋流，但自旋流方向取决于转换自旋电流的自旋方向而相反。
英文摘要
We investigate the transverse response under the out-of-plane magnetic field for magnetic heterostructures with Cu/Bi2O3 or Ag/Bi2O3 Rashba interfaces. We detect opposite contributions on the transverse resistance by the Cu/Bi2O3 and the Ag/Bi2O3 interfaces, which interestingly coincide well with the opposite signs of the spin/charge interconversion from the two interfaces. We suppose the opposite influences on the transverse resistance feature spin swapping occurrence of the converted spin current. The transverse spin flow emerges due to the spin swapping in both Cu and Ag layer, but the direction of the spin flow is opposed dependent on the spin direction of the converted spin current.
