“…In addition to the three-dimensional microwave cavities previously discussed [Fig. 2(b)], superconducting coplanar waveguide resonators, 20,75) coaxial-like cavities 76,77) and lumped-element cavities 22,[78][79][80][81][82] have been used to reach the strong coupling regime. In particular, lumped-element cavities, also used in experiments with paramagnetic spin ensembles, 15,[83][84][85][86][87] enable one to achieve larger filling factors η of the microwave cavity magnetic field within the volume of the ferromagnetic crystal compared to a three-dimensional cavity of the same frequency, leading to a larger magnetic dipole coupling strength g m c h µ -.…”

Engineered quantum systems enabling novel capabilities for communication, computation, and sensing have blossomed in the last decade. Architectures benefiting from combining distinct and complementary physical quantum systems have emerged as promising platforms for developing quantum technologies. A new class of hybrid quantum systems based on collective spin excitations in ferromagnetic materials has led to the diverse set of experimental platforms which are outlined in this review article. The coherent interaction between microwave cavity modes and collective spin-wave modes is presented as the backbone of the development of more complex hybrid quantum systems. Indeed, quanta of excitation of the spin-wave modes, called magnons, can also interact coherently with optical photons, phonons, and superconducting qubits in the fields of cavity optomagnonics, cavity magnomechanics, and quantum magnonics, respectively. Notably, quantum magnonics provides a promising platform for performing quantum optics experiments in magnetically-ordered solid-state systems. Applications of hybrid quantum systems based on magnonics for quantum information processing and quantum sensing are also outlined briefly.

Achieving quantum-level control over electromagnetic waves, magnetisation dynamics, vibrations and heat is invaluable for many practical application and possible by exploiting the strong radiation-matter coupling. Most of the modern strong microwave photon-magnon coupling developments rely on the integration of metal-based microwave resonators with a magnetic material. However, it has recently been realised that all-dielectric resonators made of or containing magneto-insulating materials can operate as a standalone strongly-coupled system characterised by low dissipation losses and strong local microwave field enhancement. Here, after a brief overview of recent developments in the field, I discuss examples of such dielectric resonant systems and demonstrate their ability to operate as multiresonant antennas for light, microwaves, magnons, sound, vibrations and heat. This multiphysics behaviour opens up novel opportunities for the realisation of multiresonant coupling such as, for example, photon-magnon-phonon coupling. I also propose several novel systems in which strong photon-magnon coupling in dielectric antennas and similar structures is expected to extend the capability of existing devices or may provide an entirely new functionality. Examples of such systems include novel magnetofluidic devices, high-power microwave power generators, and hybrid devices exploiting the unique properties of electrical solitons.

“…This variety of cavity spintronic measurement techniques which have been established since 2013 have led to a wealth of CMP exploration. For example, the ultrastrong coupling regime has been reached [51][52][53], spin wave strong coupling has been observed [49,[54][55][56], multimode cavity [57] and spin [50,[58][59][60] systems have been realized, exceptional points of the CMP eigenspectrum have been found [61,62], coherent perfect absorption has been realized [62] and the effect of Kerr nonlinearities has been studied [63,64]. Furthermore, a transition from microwave to optical frequencies has recently resulted in the exploration of cavity optomagnonics [65][66][67][68][69][70].…”

Light-matter interactions lie at the heart of condensed matter physics, providing physical insight into material behaviour while enabling the design of new devices. Perhaps this is most evident in the push to develop quantum information and spintronic technologies. On the side of quantum information, engineered lightmatter interactions offer a powerful means to access and control quantum states, while at the same time new insights into spin-photon manipulation will benefit the development of spintronic technologies. In this context the recent discovery of hybridization between ferromagnets and cavity photons has ushered in a new era of light-matter exploration at the crossroads of quantum information and spintronics. The key player in this rapidly developing field of cavity spintronics is a quasiparticle, the cavity-magnon-polariton. In this early review of recent work the fundamental behaviour of the cavity-magnon-polariton is summarized and related to the development of new spintronic applications. In the last few years a comprehensive theoretical framework of spin-photon hybridization has been developed. On an intuitive level many features can be described by a universal model of coupled oscillators, however the true origin of hybridization is only revealed by considering a more comprehensive electrodynamic framework. Here both approaches are summarized and an outline of a quantum description through the input-output formalism is provided. Based on this foundation, in depth experimental investigations of the coupled spin-photon system have been performed. For example, it has been found that hybridization will influence spin current generated through the spin pumping mechanism, demonstrating a firm link between spin-photon coupling and spintronics. Furthermore several in-situ coupling control mechanisms, which offer both physical insight and a means to develop cavityspintronic technologies, have been revealed. The many recent developments within this field represent only the first steps in what appears to be a bright future for cavity spintronics. Hopefully this early review will introduce new explorers to this exciting frontier of condensed matter research, lying at the crossroads of magnetism and cavity quantum electrodynamics.
