Spin waves are the elementary excitations of the spin system in a magnetically ordered
material state and magnons are their quasi particles. In the following article, we will discuss …

Nowadays, the interaction between phonon and magnon subsystems of a magnetic medium
is a hot topic of research. The complexity of phonon and magnon spectra, the existence of …

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 …

A supercurrent is a macroscopic effect of a phase-induced collective motion of a quantum
condensate. So far, experimentally observed supercurrent phenomena such as …

Bose–Einstein condensation of quasi-particles such as excitons, polaritons, magnons and
photons is a fascinating quantum mechanical phenomenon. Unlike the Bose–Einstein …

We calculate the effects of the spin-lattice coupling on the magnon spectrum of thin
ferromagnetic films consisting of the magnetic insulator yttrium iron garnet. The magnon …

To know the properties of a particle or a wave, one should measure how its energy changes
with its momentum. The relation between them is called the dispersion relation, which …

A macroscopic collective motion of a Bose–Einstein condensate (BEC) is commonly
associated with phenomena such as superconductivity and superfluidity, often generalised …

Weyl fermions that emerge at band crossings in momentum space caused by the spin–orbit
interaction act as magnetic monopoles of the Berry curvature and contribute to a variety of …

Ferromagnetic resonance driven spin pumping, a topic of steadily increasing interest since
its emergence over two decades ago, remains one of the most exciting research fields in …
