Outline of Final Research Achievements

This research aims to clarify an existence of complex excitation composed of spin, charge and phonon degrees of freedom in high-Tc cuprate superconductor, with utilizing quantum beams such as neutron, synchrotron X-ray and muon. The hierarchical spin excitation attributed to the localized and itinerant nature of electron was found in the hole-doped system. Furthermore, we clarified an enhancement of spin-phonon coupling by the hole-doping. On the other hand, in the electron-doped system, the evidence of spin-charge coupling was seen in the high-energy excitation. The most important result of this research is that we clarified an existence of electron-hole asymmetry in the spin and charge correlations in cuprate superconductors. The coupling among spin change and phonon is also different in the hole and electron doped systems.
