We introduce a previously unknown spin-related transport phenomenon, consisting in a transformation (swapping) of spin currents due to the spin-orbit interaction. It originates from the correlation between the spin rotation and the scattering angle. This effect is more robust than the skew-scattering, since it exists already in the first Born approximation. Swapping may lead to the spin accumulation with spin polarization perpendicular to the surface, unlike what happens in the spin Hall effect.
