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