We report the longitudinal spin-Seebeck effects (LSSEs) for Pt/Fe$$_{70}$$Cu$$_{30}$$/BiY$$_{2}$$Fe$$_{5}$$O$$_{12}$$ (BiYIG) and Pt/BiYIG devices. The LSSE voltage was found to be enhanced by inserting an ultra-thin Fe$$_{70}$$Cu$$_{30}$$ interlayer. This enhancement decays sharply with increasing the Fe$$_70$$Cu$$_30$$ thickness, suggesting that it is not due to bulk phenomena, such as a superposition of conventional thermoelectric effects, but due to interface effects related to the Fe$$_{70}$$Cu$$_{30}$$ interlayer. Combined with control experiments using Pt/Fe$$_{70}$$Cu$$_{30}$$ devices, we conclude that the enhancement of the LSSE voltage in the Pt/Fe$$_{70}$$Cu$$_{30}$$/BiYIG devices is attributed to the improvement of the spin-mixing conductance at the Pt/BiYIG interfaces.
