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 …

Rigidity of an ordered phase in condensed matter results in collective excitation modes
spatially extending to macroscopic dimensions. A magnon is a quantum of such collective …

We demonstrate large normal-mode splitting between a magnetostatic mode (the Kittel
mode) in a ferromagnetic sphere of yttrium iron garnet and a microwave cavity mode. Strong …
