摘要：

Material dependence of the spin dependent resistivity and magnetoresistance in magnetic multilayers as well as heterogeneous alloys has been studied theoretically in a two-band model, by putting emphasis on random configuration of atoms near the interfaces. When the non-magnetic atoms are on the right (left) of the magnetic atoms, e.g., Fe or Co, in the periodic table, the ratio between the spin dependent resistivity, p down arrow/p up arrow is greater (smaller) than 1. It is also shown that the two-band model unifies the results obtained in the tight-binding model and the Anderson model.
