The temperature dependence of quantum spin pumping generated using electron spin resonance with three-magnon splittings

On the basis of the Schwinger-Keldysh formalism, we have closely investigated the temperature dependence of quantum spin pumping generated using electron spin resonance. We have clarified that three-magnon splittings excite non-zero modes of magnons and characterize the temperature dependence of quantum spin pumping generated using electron spin resonance.
