| Outline of Final Research Achievements |
Strongly correlated 3d electron systems have novel physical properties due to the competition or cooperation among degrees of freedom. In this study, we have investigated localized or itinerant electron systems with multi-orbitals located in the vicinity of the metal-insulator transition to clarify the mechanism of the novel physical phenomena. We found rich physics of heavy fermion, orbital order, frustration, Fe-based superconductivity, and so on in the 3d transition metal oxides and compounds.
