Giant magnetoresistance of thin multilayers

Abstract The transport properties in magnetic ultrathin multilayers for a current in the plane configuration are considered. Using the Boltzmann approach and density functional theory, we show that the magnetoresistance for a very thin trilayer Fe–Cr–Fe exhibits an oscillatory behavior versus thickness of ferromagnetic layer and depends on the relative ratio of parameters responsible for spin-dependent scattering of electrons at interfaces and outer surfaces.
