Query: The spectroscopic signature of Kondo screening on single adatoms in
  Na(Fe0.96Co0.03Mn0.01)As   The electronic states of surface adatoms in Na(Fe0.96Co0.03Mn0.01)As have
been studied by low temperature scanning tunneling spectroscopy. The spectra
recorded on the adatoms display both superconducting coherence peaks and an
asymmetric resonance in a larger energy scale. The Fano-type line shape of the
spectra points towards a possible Kondo effect at play. The apparent energy
position of the resonance peak shifts about 5 meV to the Fermi level when
measured across the critical temperature, supporting that the Bogoliubov
quasiparticle is responsible for the Kondo screening in the superconducting
state. The tunneling spectra do not show the subgap bound states, which is
explained as the weak pair breaking effect given by the weak and broad
scattering potential after the Kondo screening.
