The spin and orbital moments for small Fe clusters deposited on a Ni(001) surface have been calculated by means of an ab initio method. We find enhanced spin and orbital moments compared to what is found in bulk Fe. Our obtained spin moments are in good agreement with previous theoretical studies on similar systems. Comparing our results with a recent x-ray magnetic circular dichroism study (Lau et al 2002 Phys. Rev. Lett. 89 057201), we find that the calculated orbital moments are much lower than those experimentally found. Reasons for this discrepancy are discussed.
