Since spin waves are angular momentum currents, they can propagate even in insulators. For spin-wave signal flow, spin-wave parametric pumping is a research technique that enables amplification in the middle of a waveguide, and has attracted much attention in recent years.
The purpose of this study is to analyze the generation process of Bose-Einstein condensation of magnons by parametric pumping using a resonator.
