Abstract

The electronic and magnetic structure of small vanadium clusters adsorbed on Ag (001) is studied as a function of the exchange integral J of the Hubbard Hamiltonian and cluster size with bcc structure. For each topological arrangement, the transition from nonmagnetic to magnetic order is characterized. As in the case of films (1 or 2 layers thick) epitaxially grown on Ag (001), antiferromagnetic coupling between V atoms is usually obtained. However, because the symmetry is lower in the present case, various magnetic configurations are displayed.
