Using a submillimeter-sized YIG (yttrium-iron-garnet) sphere mounted in a magnetic-field-
focusing cavity, we demonstrate an ultrahigh cooperativity of 1 0 5 between magnon and …

Resonant photon modes of a 5-mm-diameter yttrium iron garnet (YIG) sphere loaded in a
cylindrical cavity in the 10–30-GHz frequency range are characterized as a function of …

Hybridizing collective spin excitations and a cavity with high cooperativity provides a new
research subject in the field of cavity quantum electrodynamics and can also have potential …

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 …

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 …

Multiple-post reentrant 3D lumped cavity modes have been realized to design the concept of
a discrete Whispering Gallery and Fabry-Pérot-like Modes for multimode microwave …

Cavity optomagnonics has emerged as a promising platform for studying coherent photon-
spin interactions as well as tunable microwave-to-optical conversion. However, current …

Several experimental implementations of cavity-magnon systems are presented. First an
Yttrium Iron Garnet (YIG) block is placed inside a re-entrant cavity where the resulting hybrid …

The interaction between quantized electromagnetic fields in cavities and natural or artificial
atoms has played a crucial role in developing our understanding of light-matter interactions …

We experimentally demonstrated the strong coupling between a microwave cavity and
standing magnetostatic magnon modes in a yttrium iron garnet film. Such strong coupling …
