charging single Co atoms on ultrathin NaCl films — chenyang yuan and •yongfeng wang — Key Laboratory for the Physics and Chemistry of Nanodevices, Department of Electronics, Peking University, Beijing 100871, China.

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 3μB to 2.2μB after charge state manipulation.
