| Research Abstract |
High transition temperature superconductivity is one of the most attractive issues in the solid-state physics. In the preset study, spin and lattice dynamics were investigated by means of neutron-scattering techniques with the aim of elucidation of high-Tc mechanism. From the results obtained for various superconductors, it was revealed that two types of spin fluctuation exist in the superconducting system. Therefore, to understand the role of spin fluctuations for the high-Tc superconductivity, it is important to extract the universal feature from an entire spin fluctuation spectrum showing a multiple structure.
