摘要：

Here, we demonstrate interfacial spin-to-charge current conversion by means of spin pumping from a ferromagnetic permalloy (Py: Ni80Fe20) to a Cu/Bi2O3 interface. A clear peak owing to the spin-to-charge current conversion was observed in the voltage spectrum of a Py/Cu/Bi2O3 trilayer film, whereas no peak was observed in Py/Cu and Py/Bi2O3 bilayer films. We also found that the conversion coefficient strongly depended on the Cu thickness, reflecting the thickness-dependent momentum relaxation time for the Cu layer.
