The emerging field of cavity spintronics utilizes the cavity magnon polariton
(CMP) induced by magnon Rabi oscillations. In contrast to a single-spin quantum
system, such a cooperative spin dynamics in the linear regime is governed by the
classical physics of harmonic oscillators. It makes the magnon Rabi frequency
independent of the photon Fock state occupation, and thereby restricts the
quantum application of CMP. Here we show that a feedback cavity architecture
breaks the harmonic-oscillator restriction. By increasing the feedback photon
number, we observe an increase in the Rabi frequency, accompanied with the
evolution of CMP to a cavity magnon triplet and a cavity magnon quintuplet. We
present a theory that explains these features. Our results reveal the physics of
cooperative polariton dynamics in feedback-coupled cavities, and open up new
avenues for exploiting the light-matter interactions.
