| Outline of Final Research Achievements |
We have conducted the following research topics. (1) In iron-based ladder compound BaFe2Se3 which shows superconductivity under pressures, an orbital order is elucidated. Polar state is identified in BaFe2Se3 through a detailed determination of the space group. Dynamical magnetism in these compounds is examined by combining neutrons and muons, and characteristic timescale of spin fluctuations spanning eight orders in magnitude is quantitatively measured. (2) For the triangular antiferromagnet NiGa2S4, magnetic quadrupole correlation was clarified from neutron and Raman scattering experiments. We also elucidated the vector chirality-driven anomaly at 8.5 K through polarized neutron scattering. (3) We discovered the magnon polarization in the spintronics material Y3Fe5O12.
