In particular,\u0000two-magnon Raman scattering processes are known to generate entangled\u0000magnon-pairs with opposite momenta. We propose to harness the dynamical\u0000backaction of a driven optical cavity coupled to these processes, to obtain\u0000steady states of squeezed magnon-pairs, represented by squeezed Perelomov\u0000coherent states. The system's dynamics can be controlled by the strength and\u0000detuning of the optical drive and by the cavity losses. In the limit of a fast\u0000(or lossy) cavity, we obtain an effective equation of motion in the Perelomov\u0000representation, in terms of a light-induced frequency shift and a collective\u0000induced dissipation which sign can be controlled by the detuning of the drive.\u0000In the red-detuned regime, a critical power threshold defines a region where\u0000magnon-pair operators exhibit squeezing, a resource for quantum information,\u0000marked by distinct attractor points. Beyond this threshold, the system evolves\u0000to limit cycles of magnon-pairs. In contrast, for resonant and blue detuning\u0000regimes, the magnon-pair dynamics exhibit limit cycles and chaotic phases,\u0000respectively, for low and high pump powers.
