Hybridizing Ferromagnetic Magnons and Microwave Photons in the Quantum Limit

Hybridizing Ferromagnetic Magnons and Microwave Photons in the Quantum Limit

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 coupling is achieved in the quantum regime where the average number of thermally or externally excited magnons and photons is less than one. We …
