A Schematic Illustration of the Sample Used in the Present Study

Caption

The sample consists of a cantilever made of Y3Fe5O12(YIG) connected to an edge of a YIG film and a heater placed on the YIG film around the root of the cantilever. An electric current applied to the heater generates heat, which flows across the YIG film and the GGG substrate toward the sample holder. The heat current creates spin-wave (magnon) accumulation at the surface and the bottom of the YIG film. The accumulation injects spin current into the YIG cantilever connected around the surface of the film.
