The recently developed Drude-like model for resistivity in metallic multilayers is applied to Fe(t)/Cu(10A)/Fe(10A) trilayer systems. The basic GMR characteristics deduced conform qualitatively to reports communicated in literature. Our analyses show that the Fuchs-Sondheimer theory of thin film resistivity is not valid for layered structures and spin-dependent scattering in the bulk is the dominant mechanism for GMR in the investigated systems.
