PACS numbers: 72.10.Fk, 72.15.Lh, 73.40.Jn, 73.50.Gr, 73.50.Jt, 75.30.Vn, 75.70.Pa

Within both the Mott approximation for ferromagnetic metals and the modified Mayadas—Shatzkes model, the giant magnetoresistance effect in magnetic polycrystalline multilayers with ultrathin spacers is investigated. With the general and simple asymptotic formulas obtained, the amplitude of effect caused by the asymmetry of both the spin-dependent interface scattering of electrons and the spin-dependent transmission of electrons between the adjacent magnetic layers is estimated. The conditions, under which the effect changes the sign, are revealed, and the grain-boundary scattering influence on the giant-magnetoresistance effect amplitude is investigated too.
