We report spin-current generation related to skyrmion dynamics resonantly excited by a microwave in a helimagnetic insulator CuOSeO. A Pt layer was fabricated on CuOSeO and voltage in the Pt layer was measured upon magnetic resonance of CuOSeO to electrically detect injected spin currents via the inverse spin Hall effect (ISHE) in Pt. We found that ISHE-induced electromotive forces appear in the skyrmion phase of CuOSeO as well as in the ferrimagnetic phase, which shows that magnetic skyrmions can contribute to the spin pumping effect.
