摘要：
Numerical simulation in the recursive Green's function method is extended to a two-band tight-binding model where itinerant s- and localized d-electrons coexist. This method enables us to make more realistic calculations of the giant magnetoresistance in magnetic multilayers and granular alloys containing noble metals, such as Co/Cu and Co/Ag. By using the present method, dependence of the magnetoresistance on the size of the magnetic clusters in granular alloys is examined and compared with the experimental one as well as with that calculated before in the single-band model.
