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