We realize a cavity magnon-microwave photon system in which a magnetic dipole interaction mediates strong coupling between the collective motion of a large number of spins in a ferrimagnet and the microwave field in a three-dimensional cavity. By scaling down the cavity size and increasing the number of spins, an ultrastrong coupling regime is achieved with a cooperativity reaching 12,600. Interesting dynamic features including classical Rabi-like oscillation, magnetically induced transparency, and the Purcell effect are demonstrated in this highly versatile platform, highlighting its great potential for coherent information processing.

Coherent Conversion Between Microwave and Optical Photons—An Overview of Physical Implementations (2019, positive): “Strong coupling between magnetostatic modes and cavities has been demonstrated [91, 92, 94], but the cavity must be resonant with the optical FSR, and it is not always straightforward to realize a microwave cavity with a wide tuning range [96, 97].”
Ultrahigh cooperativity interactions between magnons and resonant photons in a YIG sphere (2015, background): “As predicted by the authors, extremely large coupling rates, g, could be achieved in YIG spheres, which is favourable for coherent information exchange and has been demonstrated experimentally later[4, 5, 22].”
