Abstract

 By scanning tunneling microscopy and spectroscopy (STM/S), the spin state of a magnetic adsorbate which shows Kondo effect on the non-metal surfaces can be explored from the Kondo resonance. Kondo resonance appears as a zero-bias anomaly in the STS spectra, and I introduce the ways to assign the zero-bias anomaly to be the Kondo resonance and to extract the information of the spin state with my recent research, the Kondo effect of iron phthalocyanine (FePc) molecules on Au(111). The control of the spin state of FePc on Au(111) by coordination chemistry is also introduced as another example.<br>
