In strongly correlated electron systems, novel phenomena can show up due to a complex combination of degrees of freedom of the electrons, such as charge, spin and orbital. To understand the mechanism of the phenomena, it is highly important to obtain information on not only static structure (crystal/magnetic structures) but also dynamical structure (lattice/spin dynamics) of materials. We utilize neutron diffraction and spectroscopy techniques which can observe dynamical susceptibility in wide spatial/temporal regimes, to explore the structure and dynamics. Several research projects including high-transition-temperature (high-Tc) superconductivity, frustrated magnetism and heavy-fermion system etc. are recently focused in our group, and we develop state-of-the-art neutron spectrometers to observe phonons and magnetic excitations. We also make every effort to grow high quality single crystals necessary for the measurements.

[Magnetic excitation from one dimensional quantum spin system]
Excitation spectrum can be obtaind by neutron-scattering measurement in a wide energy and momentum space.

[Examples of crystal growth]
High quality single crystals with large volume are grown by floating-zone traveling-solvent and chemical vapor transport methods etc.
