Cherenkov radiation of spin waves by ultra-fast moving magnetic flux quanta
Oleksandr V. Dobrovolskiy,Qi Wang,D. Yu. Vodolazov,B. Budinska,Roland Sachser,Andrii V. Chumak,M. Huth,Alexandre I. Buzdin +7 more
TL;DR: In this article, fast-moving (>1 km/s) magnetic flux quanta (Abrikosov vortices) in an adjacent Nb-C superconducting strip were used to realize the Cherenkov radiation of spin waves in a Co-Fe magnonic conduit.

Generation of Spin-Wave Pulses by Inverse Design
Silvia Casulleras,Sebastian Knauer,Qi Wang,Oriol Romero-Isart,Andrii V. Chumak,Carlos Gonzalez-Ballestero +5 more
TL;DR: In this article , the authors proposed a method to generate linear spin-wave pulses with a desired spatial-temporal profile in magnonic waveguides based on inverse design, which could lead to the utilization of large-scale magnonic circuits for classical and quantum information processing.
Spin-Wave Modes in sub-100 nm YIG Waveguides
TL;DR: In this paper, the authors discuss the progress in the realization of magnonic data processing devices, which have been studied by means of numerical simulations only, however, the developed prototypes either have millimeter or micrometer sizes.
Proceedings ArticleDOI
Width-modulated magnonic crystal and its application for spin-wave logic
A. A. Nikitin,Alexey B. Ustinov,Alexander A. Semenov,Andrii V. Chumak,Alexander A. Serga,Vitaliy I. Vasyuchka,Erkki Lähderanta,Boris A. Kalinikos,Burkard Hillebrands +8 more
TL;DR: In this article, a width-modulated dynamic magnonic crystal is developed, which utilizes a spinwave waveguide fabricated from a single-crystal Yttrium Iron Garnet film and two conducting wires attached to the film surface between modulated and unmodulated areas.

Controlling of nonlinear relaxation of quantized magnons in nano-devices
Morteza Mohseni,Qi Wang,Björn Heinz,M. Kewenig,Michael Schneider,F. Kohl,Bert Lägel,Carsten Dubs,Andrii V. Chumak,Philipp Pirro +9 more
TL;DR: In this article, the authors used space and time-resolved micro-focused Brillouin light scattering spectroscopy and micromagnetic simulations to investigate the nonlinear relaxation of strongly driven spin-waves in yttrium iron garnet nano-conduits.
