Rashba-Edelstein effect as a function of spin–orbit coupling strength. Calculated results are given for the Mn${}_1$ atom of antiferromagnetic CuMnAs with moments along the c-axis, for scaled values of the SOC, as given in the legend. a, b The results for the $\mathrm{Re}\left[{\chi }_{\mathrm{xx}}^S\right]$ and $\mathrm{Re}\left[{\chi }_{\mathrm{xy}}^S\right]$ component, respectively, of the spin REE susceptibility tensor. c, d The results for the $\mathrm{Re}\left[{\chi }_{\mathrm{xx}}^L\right]$ and $\mathrm{Re}\left[{\chi }_{\mathrm{xy}}^L\right]$ component of the orbital REE tensor, respectively, as function of electric-field frequency $\hslash \omega$.
