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