摘要：

We perform ab initio calculations for the electronic structure of 4d transition-metal clusters at the (001) surface of Ag and determine the magnetic moments. Dimers, linear chains, and plane islands are investigated, all showing a strong tendency for magnetism. We also compare our results with calculations for free clusters. Because of the hybridization with the substrate and with the adatoms in the clusters, the maximum of the moment curve is shifted to large valences. For all investigated structures Ru and Rh clusters are magnetic.
