(IMAGE) Osaka University Caption A pure spin current 'Is' is converted into a charge current 'Ic' at the Bi impurity site which has no magnetic moments but converts 'Is' into 'Ic' via its strong spin-orbit interaction. Red and blue arrows with green spheres are spins of conduction electrons (|e|) and the shadows indicate that the conduction electron spins are randomized by the localized magnetic moments at the Mn sites. The curved arrows show the motions of spin-up and spin-down electrons.
