Magnetism of 4f-atoms adsorbed on metal and graphene substrates
Result description
The electronic structure and magnetism of individual Dy atom adsorbed on the graphene/Ir(1 1 1) surface is investigated using the combination of the density functional theory with the Hubbard-I approximation to the Anderson impurity model (DFT + HIA). The divalent Dy2+ adatom is found, with the magnetic moment of 9.4-9.6 mu(B), depending on the placement of the graphene on the Ir(1 1 1) surface, in an external magnetic field. The spin and orbital magnetic moments are evaluated, and compared with the X-ray magnetic circular dichroism (XMCD) data. The positive magnetic anisotropy energy determines the out-of-plane orientation of the Dy adatom magnetic moment.
