An experimental study is made of the interactions between spin-wave modes excited in a
sphere of yttrium iron garnet by pumping the Suhl subsidiary absorption at 9.2 GHz with the …

Superconducting coplanar-waveguide resonators that can operate in strong magnetic fields
are important tools for a variety of high-frequency superconducting devices. Magnetic fields …

We investigate the coupling of an ensemble of phosphorus donors in an isotopically purified
28 Si host lattice interacting with a superconducting coplanar waveguide resonator. The …

We present a generic theoretical framework to describe nonreciprocal microwave circulation
in a multimode cavity magnonic system and assess the optimal performance of practical …

Magnon dark mode, which possesses long coherence time, has been observed in
transmission experiments of a microwave cavity loaded with two yttrium iron garnet spheres …

We report thermal control of mode hybridization between the ferromagnetic resonance and a
planar resonator (notch filter) working at 4.74 GHz. The chosen magnetic material is a …

We investigate squeezing of magnons in a conical spin spiral configuration. We find that
while the energy of magnons propagating along the k and the− k directions can be different …

The key issue for the implementation of a metamaterial is to demonstrate the existence of
collective modes corresponding to coherent oscillations of the meta-atoms. Atoms of natural …

We theoretically investigate the collective excitations of multiple (sub) millimeter-sized
ferromagnets mediated by waveguide photons. By the position of the magnets in the …

We experimentally demonstrate the operation of a Rowland-type concave grating for spin
waves, with potential application as a microwave spectrometer. In this device geometry, spin …
