Magnetism of Free and Embedded Rhodium Clusters

摘要

The electronic structures of rhodium clusters with sizes of 6, 9, 13, 19, and 43 are studied by the first-principles spin-polarized calculations within the local density functional formalism. The bondlengths of all clusters are optimized by minimizing the binding energies. The magnetic moments of the clusters are presented and compared with the experiments. The electronic structure of Rh_(43) cluster has almost the similar features of rhodium bulk. Results for the Rh clusters embedded in the nickel matrix are also presented.
