title: Charging single Co atoms on ultrathin NaCl films.
abstract: Single Co adatoms adsorbed on a double-layer NaCl film supported by Cu(111) were negatively charged after applying a positive voltage pulse to the sample in a scanning tunnelling microscope. Density functional calculations showed that the magnetic moment of Co changed from 3μBto 2.2μBafter charge state manipulation.
