摘要：

Size-dependent, magnetic, and structural properties of fee Rh, and RUN clusters (N=13, 19, 43, 55, and 79) are calculated using a tight-binding Hubbard Hamiltonian in the unrestricted Hartree-Fock approximation. Results for the magnetic moment, cohesive energy, and interatomic distance at T=0 are given as functions of cluster size. The magnetic-nonmagnetic transitions estimated are in agreement with experimental findings.
