The transport properties of ultrathin metallic sandwich structures of Fe/Cr/Fe are studied as a function of magnetic layers thickness for the current in plane geometry (CIP). Taking into account the band structure obtained from the density functional theory (DFT), we determine the basic physical properties like Fermi energy and relaxation time calculated for each magnetic and spacer layer. Next, using the Boltzmann formalism in its extended form we obtain the results for the magnetoresistance (MR). In particular, we analyze an influence of the effective mass parametrization.
