Overview

abstract

• Size-dependent, magnetic and structural properties of small RuN clusters are calculated using a tight-binding Hubbard Hamiltonian in the unrestricted Hartree-Fock approximation. The calculated average magnetic moment shows very strong oscillations as a function of the cluster size, which is in contrast with the almost independent behavior previously found in the iron-group clusters. Small cohesive energy differences are found between isomers while on the contrary, the magnetic moments differ considerably. Our results are in agreement with the existing experimental measurements. © 1998 Elsevier Science B.V. All rights reserved.
