在扫描隧道显微镜中对样品施加正电压脉冲后，吸附在由铜(111)支撑的双层氯化钠薄膜上的单个钴原子带负电荷。密度泛函计算表明，电荷态处理后，Co的磁矩从3μB变为2.2μB。
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.
