Abstract

The electronic structure of Co/Cu(001) and Fe/Cr(001) magnetic multilayers has been investigated within the local density approximation combined with dynamical mean field theory. Our calculation shows enhanced density of states at the Fermi level, suggesting that electronic correlations might play an important role in the transport properties of multilayers.
