“…Based on the low damping and the flexible controllability of the system, the magnonic second-order sideband presented here possesses the features of narrow linewidth and convenient control. Beyond fundamental scientific significance, our results may have potential applications in high-precision measurement, such as force sensors [55], magnetostrictive transducers [56] and actuators [57].…”

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.

“…Considering the magnetoresistance of the magnetostrictive rod and the magnetic conductor (output rod, shell, and base), as well as magnetic leakage and the magnetic flux between the coils, the equivalent magnetic circuit model of the actuator was established [28], as shown in figure 4. The magnetostrictive rod is divided into eight sections (rod1∼ rod8) according to the position of the coils.…”

Active combustion control (ACC) technology is an effective measure for suppressing the combustion oscillation of aero-engines. The magnetostrictive actuator is the most suitable choice for the ACC actuator due to its excellent high-frequency characteristics and high-temperature resistance. For the magnetostrictive actuator to produce high-frequency displacement, the constant current driver must have sufficient power, which increased its mass. A solution is to use multi-channel and low-power constant current driver. Therefore, the coil of the magnetostrictive actuator is axially dispersed and driven by two four-channel servo amplifiers. The driver's mass is significantly reduced while maintaining the same electromagnetic conversion effect. In addition, an analytical model of a discrete coil magnetostrictive actuator is established, and a series of experiments are conducted. The maximum hysteresis error of output displacement at 200 Hz is reduced by 15.2%. Furthermore, under PID closed-loop control, the root mean square (RMS) error is less than 2% when tracking a 10 Hz sinusoidal displacement with coil switching drive.
