We report the longitudinal spin-Seebeck effects (LSSEs) for Pt/FeCu/BiY
Fe
O
(BiYIG) and Pt/BiYIG devices. The LSSE voltage was found to be enhanced by inserting an ultra-thin FeCu interlayer. This enhancement decays sharply with increasing the Fe
Cu
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 FeCu interlayer. Combined with control experiments using Pt/FeCu devices, we conclude that the enhancement of the LSSE voltage in the Pt/FeCu/BiYIG devices is attributed to the improvement of the spin-mixing conductance at the Pt/BiYIG interfaces.
