Magnon-polariton(MP) is the coherent coupled (strong coupled) state between a photon and a magnon(quantized spin wave) in a resonator.In this study, we investigate coherent microwave oscillation of MP in the ultra-strong coupled regime based on a circuit model. It is found that in the ultra-strong coupled state, the gain given to the circuit (photon) is transferred to the magnon through the coupling, then magnon can automatically oscillate.This is the principle of spin oscillation based on quantum hybrid technology.
