Abstract
In the magnetic molecules adsorbed on metalic surfaces, the interference of the Kondo effect and molecular characteristics gives rise to novel physical phenomena. As examples, I introduce my recent studies; the Kondo effect originating from the coupling of the spin and orbital degrees of freedom in an iron phthalocyanine molecule on Au(111), and the extended underscreened Kondo resonance induced by the collective molecular spin state resulting from the strong π-d interaction in a manganese phthalocyanine molecule on Pb(111).
