N2 - The magnetic properties of Fe/Nb multilayers have been studied for the first time by means of the full-potential linearized augmented-plane-wave method. It has been found that a Nb(001) monolayer is magnetic with a moment of 1.89μB per atom, whereas 2Nb(001) and 3Nb(001) slabs are nearly nonmagnetic. The evolution of magnetism for Nb from monolayer to bulk is rapid. Fe/Nb(001)is nearly nonmagnetic, 3Nb/Fe/3Nb(001) is magnetically dead, 2Nb/3Fe/2Nb(001) is magnetically active with a large moment, and Nb layers are antiferromagnetically coupled with Fe layers. The tendency that the thinner Fe layers are magnetically dead, and the thicker Fe layers magnetically active, is found, in agreement with recent experiments.
