| Outline of Final Research Achievements |
Iron-based superconductors, LaFeAsO1-xHx, has the two superconducting (SC) phases and two anti-ferromagnetic (AFM) phases. From the transport properties and first-principle calculations, it was shown that the half-filled state of Fe-3dxy orbital strongly affects the normal-conduction properties, and contributes the appearance of AFM in the proximity of the higher critical temperature (Tc) SC phase. These results indicate that the high-Tc superconductivity may emerge in the proximity of the half-filled state of Fe-3dxy, which provides a new design concept for the high-Tc superconductor.
