Outline of Final Research Achievements

We have studied spin wave of yttrium iron garnet (YIG) crystal with high performance for spin Seebeck effect under temperature gradient by inelastic neutron scattering spectrometers, 4SEASONS and AMATERAS at J-PARC/MLF. The low energy spin wave intensity measured at (220) magnetic Bragg peak position showed a little increase to the opposite direction at +q and -q points under a temperature gradient less than 1.4K/mm. The observed change was comparable to error bar. During a series of our study, extremely wide energy range of YIG spin wave from about 10 microeV to 90 meV (upper boundary) is successfully explored for the first time by using state-of-the-art inelastic neutron scattering spectrometers, DNA, AMATERAS, and 4SEASONS at J-PARC/MLF.
