Final Report for Contract N00014-89-J-1157 (University of Illinois)

Abstract

We perform both first-principle and empirical tight-binding calculations on the band structures of metal-metal and metal-semiconductor superlattices. The materials of interest include superlattices made of transition-metals (Fe,Co)/Cu, Fe/Cr), rare earths (GD/Y, DY/Y, Er/Y) and semimetal-semiconductor combinations (Er, Gd)As/(Al,Ga)As). The conduction electron mediated indirect exchange interaction (RKKY interaction) between magnetic atoms in these superlattices is calculated. The transport properties of these superlattices have also been studied
