A researcher whose work with Alain Schuhl explains giant magnetoresistance through spin-dependent conduction in magnetic multilayers. In the Mott two-current model, the two electron spin channels can carry electric current with different resistances. Changing the relative magnetization directions of adjacent layers changes how strongly each channel is scattered. Their treatment connects microscopic scattering with a measurable resistance change and makes explicit the assumptions needed to treat the spin channels independently.[ref]
