✦ Synopsis

We present a simple theoretical description of recently measured giant magnetoresistance effects in Fe/Cr layered structures. The resistivity is calculated by solving the Boltzmann transport equation with spin-dependent scattering at the interfaces. The magnitude of the effect depends on the ratio of the layer thickness to the mean free path and on the asymmetry in scattering from spin-up and spin-down elec- trons. Good agreement with experiment is found for both sandwich structures and superlattices.
