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 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 layers, but the direction of the spin flow is opposed depending on the spin direction of the converted spin current.We investigate the transverse response under the out-of-plane magnetic field for magnetic heterostructures with Cu/Bi2O3 or Ag/Bi2O3 Rashba interfaces.

具有 Rashba 界面的磁性异质结构中横向电阻调制的自旋交换证据

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 界面对横向电阻的相反贡献，有趣的是，这与来自两个界面的自旋/电荷相互转换的相反符号很好地吻合。我们假设对横向电阻特征的相反影响是转换自旋电流的自旋交换发生。由于 Cu 层和 Ag 层中的自旋交换，出现了横向自旋流，但自旋流的方向取决于转换后的自旋电流的自旋方向。我们研究了面外磁场下的横向响应具有 Cu/Bi2O3 或 Ag/Bi2O3 Rashba 界面的磁性异质结构的磁场。我们检测到 Cu/Bi2O3 和 Ag/Bi2O3 界面对横向电阻的相反贡献，有趣的是，这与来自两个界面的自旋/电荷相互转换的相反符号很好地吻合。我们假设对横向电阻特征的相反影响是转换自旋电流的自旋交换发生。由于 Cu 和 Ag 层中的自旋交换，出现横向自旋流，但自旋流的方向相反，这取决于转换后的自旋流的自旋方向。我们假设对横向电阻特征的相反影响是转换自旋电流的自旋交换发生。由于 Cu 和 Ag 层中的自旋交换，出现横向自旋流，但自旋流的方向相反，这取决于转换后的自旋流的自旋方向。我们假设对横向电阻特征的相反影响是转换自旋电流的自旋交换发生。由于 Cu 和 Ag 层中的自旋交换，出现横向自旋流，但自旋流的方向相反，这取决于转换后的自旋流的自旋方向。
