英文摘要
High temperature superconductivity occurs as a result of cooperation of spin and charges. We performed neutron scattering and resonant inelastic x-ray scattering (RIXS) complementarily to understand excited states of spin and charges in high-Tc cuprates. We clarified a universal charge excitation in metallic regime by RIXS. In addition we clarified itinerant electrons plays an important role in magnetic correlation in metallic regime by neutron.
