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]

Alain Schuhl and Daniel Lacour's authored article in C. R. Physique6,pp.945–955. Section2.1 discusses Mott two-current model transport parameters and the spin asymmetry of defect scattering;§2.2 describes averaging scattering when carriers sample several layers. This supports the model qualifications without asserting a universal iron channel ordering.
