The effect of spillover in the electronic and magnetic properties of Ni, Co, and Fe clusters

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 260 atoms making use of symm...
