Query: Trends in magnetism of free Rh clusters via relativistic ab-initio
  calculations   A fully relativistic ab-initio study on free Rh clusters of 13-135 atoms is
performed to identify general trends concerning their magnetism and to check
whether concepts which proved to be useful in interpreting magnetism of 3d
metals are applicable to magnetism of 4d systems. We found that there is no
systematic relation between local magnetic moments and coordination numbers. On
the other hand, the Stoner model appears well-suited both as a criterion for
the onset of magnetism and as a guide for the dependence of local magnetic
moments on the site-resolved density of states at the Fermi level. Large
orbital magnetic moments antiparallel to spin magnetic moments were found for
some sites. The intra-atomic magnetic dipole Tz term can be quite large at
certain sites but as a whole it is unlikely to affect the interpretation of
x-ray magnetic circular dichroism experiments based on the sum rules.
