| Outline of Final Research Achievements |
Observation of microscopic ordering and fluctuation are indispensable for revealing non-trivial electronic states in materials, for example, itinerant-localized transition, multipole ordering, and superconductivity in the vicinity of magnetic and charge ordered regions. Neutron scattering techniques, which have been applied for such studies, are progressing owing to recent upgrade of sources and production of high flux beam. In the present study, we attempted to perform previously unexplored measurements of the Brillouin scattering and polarized neutrons, and revealed dual nature of itinerant-localized state on the Kondo lattice systems, phase diagram and magnetic excitations of Fe-based superconductors, microscopic study of Weyl fermions, and so on.
