The electronic structure and magnetism of individual Dy atom adsorbed on the (111) surface of Ir is investigated using the combination of the density functional theory with the Hubbard-I approximation to the Anderson impurity model (DFT + HIA). The Dy3+ adatom is found magnetic with the magnetic moment of 9: 35 mu(B) in the external magnetic field. The spin and orbital magnetic moments, and their ratio are evaluated, and compared with the X-ray magnetic circular dichroism data. The positive magnetic anisotropy energy of approximate to 1.3 meV determines the out-of-plane orientation of the Dy adatom magnetic moment.
