TL;DR: The Roadmap on Magnonics as mentioned in this paper is a collection of 22 sections written by leading experts in this field who review and discuss the current status but also present their vision of future perspectives.
Journal ArticleDOI
Magnon–fluxon interaction in a ferromagnet/superconductor heterostructure
Oleksandr V. Dobrovolskiy,Roland Sachser,Thomas Brächer,T. Böttcher,T. Böttcher,V. V. Kruglyak,Ruslan V. Vovk,Valerij A. Shklovskij,Michael Huth,Burkard Hillebrands,Andrii V. Chumak +10 more
TL;DR: In this paper, the magnon frequency spectrum exhibits a Bloch-like band structure that can be tuned by the biasing magnetic field and Doppler shifts in the frequency spectra of spin waves scattered on a flux lattice.
Journal ArticleDOI

TL;DR: In this paper, a magnonic directional coupler based on yttrium iron garnet single-mode waveguides of 350 nm width has been proposed to encode information and guide it to one of the two outputs of the coupler depending on the signal magnitude, frequency, and the applied magnetic field.

Magnon-Fluxon interaction in a ferromagnet/superconductor heterostructure
Oleksandr V. Dobrovolskiy,Roland Sachser,Thomas Brächer,Thomas Fischer,V. V. Kruglyak,Ruslan V. Vovk,Valerij A. Shklovskij,Michael Huth,Burkard Hillebrands,Andrii V. Chumak +9 more
TL;DR: In this article, it was shown that the magnon frequency spectrum exhibits a Bloch-like band structure which can be tuned by the biasing magnetic field, and Doppler shifts in the frequency spectra of spin waves scattered on a flux lattice moving under the action of a transport current in the superconductor.
