  • By using neutron scattering technique, we are studying strongly correlated electron systems, mainly CeMIn5 (M=Co, Rh,Ir), Mott insulators (Ti and Mn systems), Sr2RuO4, RENi2B2C (RE=Y and rare earth) and their relatives. Recent progress in my research activity is summarized as follows:

    (1)Superconducting properties in CeMIn5 (M=Co, Rh,Ir)
    FFLO state has been proposed to realize in quasi-two dimensional heavy electron superconductor CeCoIn5. Then we have tried to verify it by SANS experiments.

    (2) Superconducting symmetry in Sr2RuO4
    Sr2RuO4 has been suggested to be a spin triplet superconductor. The system posses a huge incommensurate AFM spin fluctuations at q =(1/3 1/3 L) but any direct evidence of ferromagnetic spin fluctuations has not been reported so far. We plan to perform SANS experiments on this material. Then we tried to grow new single crystals.
