“…Among all HQSs, the HQS based on collective spin excitations (magnons) in magnetic materials, e.g. yttrium iron garnet (YIG), has attracted great attention and made significant progress over the past decade; see relevant reviews [4][5][6][7][8][9][10][11][12]. As one of the main advantages, the magnonic system exhibits an excellent ability to coherently interact with diverse quantum systems, including microwave photons [13][14][15][16][17][18], optical photons [19][20][21][22], vibration phonons [23][24][25][26], and superconducting qubits [27][28][29][30].…”

“…Up to now, although there have been exhaustive reviews on the interactions between magnons and microwave cavity photons, optical cavity photons, and superconducting qubits [4,8,9], and on the configurations, circuits and materials for realizing the HQS based on magnons [5,7,10,12], there is a lack of a thorough review on the field of cavity magnomechanics (CMM), which studies the interactions among magnons, microwave cavity photons, and vibration phonons [23][24][25][26]. The present review exactly fills this gap, which includes underlying theories of the magnomechanical coupling, up-to-date experimental observations, and abundant theoretical studies/protocols, covering both classical and quantum phenomena in the field of CMM.…”

Hybrid quantum systems based on magnons in magnetic materials have made significant progress in the past decade. They are built based on the couplings of magnons with microwave photons, optical photons, vibration phonons, and superconducting qubits. In particular, the interactions among magnons, microwave cavity photons, and vibration phonons form the system of cavity magnomechanics (CMM), which lies in the interdisciplinary field of cavity QED, magnonics, quantum optics, and quantum information. Here, we review the experimental and theoretical progress of this emerging field. We first introduce the underlying theories of the magnomechanical coupling, and then some representative classical phenomena that have been experimentally observed, including magnomechanically induced transparency, magnomechanical dynamical backaction, magnon-phonon cross-Kerr nonlinearity, etc. We also discuss a number of theoretical proposals, which show the potential of the CMM system for preparing different kinds of quantum states of magnons, phonons, and photons, and hybrid systems combining magnomechanics and optomechanics and relevant quantum protocols based on them. Finally, we summarize this review and provide an outlook for the future research directions in this field.

“…Here, we compare the spin coupling to microwave resonators with that resulting from magnonic cavities (both saturated ferromagnets and flux-closure states). In the case of magnons, we base our calculations on three archetypical materials, common in the field of quantum magnonics: − On the one hand, a ferrimagnetic garnet with record low damping but low saturation magnetization (YIG, with Gilbert damping parameter α ∼ 10 –4 ). On the other hand, two ferromagnets with larger magnetization but higher damping, i.e., Co 25 Fe 75 alloy (CoFe, with α ∼ 10 –3 ) and Permalloy (Py, with α ∼ 0.5 × 10 –2 ), the most widely used soft-ferromagnet for spin-wave-based applications.…”

Performing nanoscale scanning electron paramagnetic resonance (EPR) requires three essential ingredients: First, a static magnetic field together with field gradients to Zeeman split the electronic energy levels with spatial resolution; second, a radio frequency (rf) magnetic field capable of inducing spin transitions; finally, a sensitive detection method to quantify the energy absorbed by spins. This is usually achieved by combining externally applied magnetic fields with inductive coils or cavities, fluorescent defects, or scanning probes. Here, we theoretically propose the realization of an EPR scanning sensor merging all three characteristics into a single device: the vortex core stabilized in ferromagnetic thin-film discs. On one hand, the vortex ground state generates a significant static magnetic field and field gradients. On the other hand, the precessional motion of the vortex core around its equilibrium position produces a circularly polarized oscillating magnetic field, which is enough to produce spin transitions. Finally, the spin−magnon coupling broadens the vortex gyrotropic frequency, suggesting a direct measure of the presence of unpaired electrons. Moreover, the vortex core can be displaced by simply using external magnetic fields of a few mT, enabling EPR scanning microscopy with large spatial resolution. Our numerical simulations show that, by using low damping magnets, it is theoretically possible to detect single spins located on the disc's surface. Vortex nanocavities could also attain strong coupling to individual spin molecular qubits with potential applications to mediate qubit−qubit interactions or to implement qubit readout protocols.

“…The heart of these applications is the designing of coherent couplings between different degrees of freedom in these hybrid systems. Cavity magnomechanics has emerged as an ideal platform to study the coherent interactions between photons, phonons, and magnons [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Fascinating applications have been envisioned, such as low-temperature thermometer [21], quantum memory for photonic quantum information [22], and building block for long-distance quantum network [23].…”

Cavity magnomechanics has become an ideal platform to explore macroscopic quantum effects. Bringing together magnons, phonons, and photons in a system, it opens many opportunities for quantum technologies. It was conventionally realized by an yttrium iron garnet, which exhibits a parametric magnon-phonon coupling $\hat{m}^\dag\hat{m}(\hat{b}^\dag+\hat{b})$, with $\hat{m}$ and $\hat{b}$ being the magnon and phonon modes. Inspired by the recent realization of two-dimensional (2D) magnets, we propose a cavity magnomechanical system using a 2D magnetic material with both optical and magnetic drivings. It features the coexisting photon-phonon radiation-pressure coupling and quadratic magnon-phonon coupling $\hat{m}^\dag\hat{m}(\hat{b}^\dag+\hat{b})^2$ induced by the magnetostrictive interaction. A stable squeezing of the phonon and bi- and tri-partite entanglements among the three modes are generated in the regimes with a suppressed phonon number. Compared with previous schemes, ours does not require any extra nonlinear interaction and reservoir engineering and is robust against the thermal fluctuation. Enriching the realization of cavity magnomechanics, our system exhibits its superiority in quantum-state engineering due to the versatile interactions enabled by its 2D feature.
