Abstract
Using a tight-binding model with electron-electron interactions we sho w that the magnetic states of 4d transition metal clusters are stabili zed by the Hund's rule exchange interaction. Taking realistic paramete rs we obtained magnetic states for Pd-13, Rh-13 and Ru-13 clusters whi ch agrees qualitatively with the recent experimental data and with oth er calculations. The interatomic distances increase by up to similar t o 7% between nonmagnetic and magnetic clusters.
