A brief overview is presented how neutron inelastic scattering method has been applied to the study on Cu oxide high-Tc superconductors. Here, we mainly show results of the measurements carried out on the YBa2Cu3O6+x (Y123 system), and demonstrate how these works have presented meaningful information to identify the origin of the superconductivity and underlying unusual dynamical behaviors related to its active magnetism, which originates from the fact that the system is induced from the Mott-insulating state by doping holes (or electrons).

Key words: Neutron inelastic scattering; Y123 system; Cu-oxide high temperature supeconductors; Magnetic excitations; Phonons
