  • We report spin-current generation related to skyrmion dynamics resonantly excited by a microwave in a helimagnetic insulator Cu2OSeO3. A Pt layer was fabricated on Cu2OSeO3 and voltage in the Pt layer was measured upon magnetic upon magnetic resonance of Cu2OSeO3 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 Cu2OSeO3 as well as in the ferrimagnetic phase, which shows… CONTINUE READING
