dc.description.abstract
We show that the magnetic state of individual manganese phthalocyanine (MnPc)
molecules on a Bi(110) surface is modified when the Mn2+ center coordinates to
CO molecules adsorbed on top. Using scanning tunneling spectroscopy we
identified this change in magnetic properties from the broadening of a Kondo-
related zero-bias anomaly when the CO-MnPc complex is formed. The original
magnetic state can be recovered by selective desorption of individual CO
molecules. First principles calculations show that the CO molecule reduces the
spin of the adsorbed MnPc from S=1 to S=1/2 and strongly modifies the
respective screening channels, driving a transition from an underscreened
Kondo state to a state of mixed valence.
