The electronic configurations of Fe, Co, Ni and Cu adatoms on graphene and graphite have been studied by x-ray magnetic circular dichroism and charge transfer multiplet theory. A delicate interplay between long-range interactions and local chemical bonding is found to influence the adatom equilibrium distance and magnetic moment. The results for Fe and Co are consistent with purely physisorbed species having, however, different 3 d -shell occupations on graphene and graphite ( ${{d}^{n+1}}$ and ${{d}^{n}}$ , respectively). On the other hand, for the late 3 d metals Ni and Cu a trend towards chemisorption is found, which strongly quenches the magnetic moment on both substrates. |
