Abstract:
We calculate the electronic structure of 3d transition-metal clusters with a model Hamiltonian that takes into account electron spillover at the cluster surface and uses bulk parameter values for the interactions. We perform calculations for fcc and bcc clusters of up to 177 atoms making use of symmetry properties. We obtain magnetic moments and ionization potentials for Ni, Co, and Fe clusters, and compare with different experimental results inferring that the essential features of the electronic and magnetic properties are reproduced, starting from an spd-bulk parametrization, if a realistic approach for electron spillover is considered.
