Abstract
Ab initio calculations of the electronic and magnetic properties of me tallic nanostructures on (001) surfaces of Cu and Ag are presented. Th e LDA approximation of the density functional theory and the KKR-Green 's function method are used. It is shown that 3d, 4d and 5d small clus ters can be magnetic on metal surfaces. The effect of intermixing with the substrate on the magnetic properties is investigated for Fe clust ers on Cu(001). The influence of the geometry and the size of the clus ters on the magnetic properties of 46 clusters is shown. Sizeable magn etic moments for 56 clusters are found on the Ag surface.
