Calculations based on first principles showed that 3d transition-metal atoms can have strong magnetic moments on the surface of Cu(001). Surface magnetism, however, is not limited to the impurities. Substantial moments were also derived from the calculations for surface Cu atoms which are nearest to the impurities. This suggests that the Cu atoms can somehow be “magnetized” at the surface, offering interesting a local magnetism for further exploitation.
