We present spin pumping using a Heusler alloy Co2 MnSi /Pt bilayer film. A spin current is produced by a ferromagnetic resonance (FMR) technique. The pure spin current injected into the Pt layer from the Co 2 MnSi layer is detected by the inverse spin-Hall effect (ISHE), which converts the spin current into an electric current. We estimated a damping constant of the Co2 MnSi /Pt bilayer film from an angular dependence of FMR spectra. Using the damping constant efficiency of spin pumping from the Co2 MnSi layer is evaluated. We found that a mixing conductance at the Co2 MnSi /Pt interface is comparable to that at a permalloy/Pt interface.
