Magnetism and electronic structure of a Dy adatom on a MgO(001) substrate
Original language description
The electronic structure and magnetism of an individual Dy atom adsorbed on the MgO(001) substrate isinvestigated using a combination of the density functional theory with the Hubbard-I approximation to the Anderson impurity model. The divalent Dy2+ adatom in f10 configuration is found. The calculated x-ray absorption and magnetic circular dichroism spectra are compared to the experimental data. Quantum tunneling between degenerate|J=8.0,Jz=±4.0〉states leads to the formation of a|J=8.0,Jz=0.0〉ground state withan in-plane orientation of the magnetic moment. It explains the absence of remanent magnetization in a Dy adatom on the top of the MgO(001) substrate. Our studies can provide a viable route for further investigation and prediction of the rare-earth single-atom magnets.
