| Outline of Final Research Achievements |
Neutron scattering technique is the best probe for the determination of material structures and the observation of microscopic dynamics. It has, thus, been widely used for the observation of spin correlation and elementary excitation in novel quantum states. Though the unpolarized neutron has been the main stream for inelastic neutron scattering, the use of polarized neutron brings much more information such as separation of magnetic and phonon excitations, observation of hybrid magneto-lattice excitation, etc. In this project our goal was to develop the polarized inelastic neutron scattering spectrometer, to make collection of high-quality data possible, and to reveal the nature of novel quantum states. We implemented supermirror polarization device on the existing spectrometer. At present we are waiting for JRR3. Meanwhile we proceed neutron scattering study on quantum spin system, multiferroic materials, and frustration systems by using J-PARC/MLF and neutron facilities abroad.
