Ab-Initio Band Structure Calculation for Magnetic Multilayers
Abstract
The magnetic properties of magnetic multilayers are studied using first principles total energy calculations. In this paper we present our results for bcc Fe multilayers with a (001) stacking direction. Using Nb as a spacer material we find an oscillating exchange coupling with a period of about 4.6 Å( ≈3 Nb monolayers). A detailed study of the magetic moments in the Nb spacer is given. Furthermore we discuss the dependence of the exchange coupling strength as a function of the thickness of the Fe slabs.
