The electronic structures of rhodium clusters with sizes of 6, 9, 13, 19, and 43 are studied by first-principles spin-polarized calculations within the local-density-functional formalism. The bond lengths of all clusters are optimized by minimizing the binding energies. The magnetic moments of the clusters are presented and compared with experiments. The electronic structure of the Rh43 cluster has almost the same features as bulk rhodium.
