“…For example, strong coupling has now been achieved using the ferromagnetic metal permalloy, important for nanoscale spintronic development, 39,40 and several antiferromagnets. [43][44][45]54 From the cavity perspective, all that is required is a well defined resonance; 55 a variety of unique 3D cavity designs 28,29,[56][57][58][59][60] and 2D resonators 26,32,[61][62][63] have been used. Often cavity modes with quality factor Q 1000 are desired to help achieve high cooperativity.…”

Strong interactions between magnetic materials and electrodynamic cavities mix together spin and photon properties, producing unique hybridized behaviour. The study of such coupled spin-photon systems, known as cavity magnonics, is motivated by the flexibility and controllability of these hybridized states for spintronic and quantum information technologies. In this tutorial we examine and compare both coherent and dissipative interactions in cavity magnonics. We begin with a familiar case study, the coupled harmonic oscillator, which provides insight into the unique characteristics of coherent and dissipative coupling. We then examine several canonical cavity magnonic systems, highlighting the requirements for different coupling mechanisms, and conclude with recent applications of spin-photon hybridization, for example, the development of quantum transducers, memory architectures, isolators and enhanced sensing.
