✦ Synopsis

Using low-temperature scanning tunnelling spectroscopy we investigate electron scattering from isolated Ce adatoms on Ag(111). dI/dV tunnelling spectra reveal a characteristic antiresonance around the Fermi energy which is not observed for nonmagnetic Ag adatoms. We interpret this spectrum as a Fano interference between delocalised sp-derived Ag states and the localised f-derived Kondo resonance.

The Kondo effect arises from the quantum mechanical interplay between the electrons of a host metal and a magnetic impurity and is predicted to result in local charge and spin variations around the magnetic impurity. A cryogenic scanning tunneling microscope was used to spatially resolve the electro
