Upper panel: Diffusion current densities when only the spin-drag effect is included (solid lines). A dashed line shows a current density when interaction is ignored. Lower panel: Diffusion current densities when both of spin-drag and bandgap narrowing effects are included. , (,) for spin-up electrons (spin-down electrons) and , for the total current. A density gradient of , , is assumed. Positive values mean that electrons flow from high density to low density.
