| Outline of Final Research Achievements |
First, spin wave heat conveyer effect was investigated on an yttrium iron garnet (YIG) sample as a function of excited spin-wave frequencies. At lower frequency the heat conveyer effect was observed localized at the sample end. At higher frequency, the effect was observed shift to inner position from the sample end. Second, spin transfer torque was applied to spin waves by spin Hall effect through the Pt and/or W film evaporated on the YIG sample by flowing a current. The modulated spin-wave heat conveyer effect was observed at the sample end by using infrared camera. This observed effect is possible to be originated from spin Hall effect.
