We report temperature evolution of spin-charge conversion through the inverse Rashba-Edelstein effect (IREE) in a metallic heterostructure. The IREE was induced in a Ag/Bi junction by spin pumping, dynamical spin injection from a ferromagnetic metal; nonequilibrium spin accumulation created in the Ag/Bi junction is converted into a charge current at the interface. By measuring the charge current arising from the IREE at different temperatures, we found that the spin-charge conversion efficiency is almost independent of temperature. This method offers a versatile route for probing the spin-orbit coupling at metallic interfaces under various conditions, promising further development of spin-orbit physics and spin-based technologies.
