We study the generation of a magnon blockade in a single-crystalline yttrium-iron-garnet
(YIG) sphere coupled to a three-dimensional superconducting microwave resonator that …

Brillouin light scattering is an established technique to study magnons, the elementary
excitations of a magnet. Its efficiency can be enhanced by cavities that concentrate the light …

Nonreciprocal devices that allow unidirectional wave propagation are indispensable in
many scientific fields, including, for example, optics, acoustics, electronics, and …

We experimentally investigate magnon polaritons arising in ferrimagnetic resonance
experiments in a microwave cavity with a tunable quality factor. To this end, we …

Cavity magnonics deals with the interaction of magnons—elementary excitations in
magnetic materials—and confined electromagnetic fields. We introduce the basic physics …

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 …

We demonstrate the long-range strong coupling of magnetostatic modes in spatially
separated ferromagnets mediated by a microwave frequency cavity. Two spheres of yttrium …

The new field of spin cavitronics focuses on the interaction between the magnon excitation
of a magnetic element and the electromagnetic wave in a microwave cavity. In the strong …

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

The dissipative light-matter coupling can cause the attraction of two energy levels, ie, level
attraction, when competing with the coherent coupling that induces usual Rabi-level …
