| Outline of Final Research Achievements |
In order to reveal the magnetism in the molecules adsorbed on metal surface, we have developed theoretical method which can treat both characteristics of molecules and electron correlation effect, and apply this method to the elucidation of the Kondo effect, magnetic anisotropy in molecular-surface systems.
we have succeeded to build a flexible and efficient Numerical renormalization group simulation code which can handle various Kondo models. By using this code, I have carried out theoretical studies of magnetism in transition metal phthalocyanine on metal surfaces, for example, the Kondo effect induced by the collective spin in Mn-phthalocyanine molecule on Pb(111) surface, and competition between the spin-orbit interaction and the Kondo effect in Fe-phthalocyanine molecule on Au(111) surface.
