“…The magnetostrictive effect describes the phenomenon that, when the magnon mode in the YIG sphere is excited, the varying magnetization induced by the magnon excitation leads to geometrical deformation of the YIG sphere, which can be treated as a mechanical resonator [19]. Currently, the magnomechanical system [20][21][22][23][24], which describes the coherent coupling between magnon modes and mechanical modes (phonons) in the YIG sphere via the magnetostrictive effect, has attracted extensive attention in the magnonic field and many exciting advances have been achieved, These include achieving magnon-photon-phonon entanglement [25][26][27], mechanical bistability [28], nonreciprocal transmission [29][30][31][32], squeezing of the microwave field [33], and magnonic frequency combs [34][35][36]. On the other hand, non-Hermitian cavity magnonics has also aroused considerable interest and has emerged as a new frontier in the magnonic field [37][38][39][40].…”

Nonlinear interaction between the magnon mode and the mechanical mode in a magnomechanical system is treated analytically where the magnon mode is coherently driven by a bichromatic microwave drive field consisting of a strong pumping field and a weak probe field and that works within a perturbative regime. Using experimentally achievable parameters, we show that the magnonic second-order sideband is generated and can be considerably enhanced by increasing the power of the pumping field. The suppression of the magnonic second-order sideband generation at the resonance point is discussed. Furthermore, the efficiency of magnonic second-order sideband generation can be well controlled by adjusting the applied bias magnetic field strength, which is a particular feature compared to the optical second-order sideband. In addition to offering insights into the magnomechanical nonlinearity, the present results have the potential to pave the way for exploring practical applications for achieving high-precision measurement in magnonics.
