Thomas Fischer,M. Kewenig,Dmytro A. Bozhko,Alexander A. Serga,Ihor I. Syvorotka,Florin Ciubotaru,Christoph Adelmann,Burkard Hillebrands,Andrii V. Chumak +8 more
TL;DR: In this paper, the authors present the experimental realization of a majority gate based on the interference of spin waves in an Yttrium-Iron-Garnet-based waveguiding structure.
Journal ArticleDOI
Spin Pinning and Spin-Wave Dispersion in Nanoscopic Ferromagnetic Waveguides.
Qi Wang,Björn Heinz,Roman Verba,M. Kewenig,Philipp Pirro,Michael Schneider,Thomas J. Meyer,Bert Lägel,Carsten Dubs,Thomas Brächer,Andrii V. Chumak +10 more
TL;DR: A critical width is found, below which the exchange interaction suppresses the dipolar pinning phenomenon and changes the quantization criterion for thespin-wave eigenmodes and results in a pronounced modification of the spin-wave characteristics.
Journal ArticleDOI
Propagation of Spin-Wave Packets in Individual Nanosized Yttrium Iron Garnet Magnonic Conduits.
Björn Heinz,Thomas Brächer,Michael Schneider,Qi Wang,Qi Wang,Bert Lägel,Anna M. Friedel,David Breitbach,Steffen Steinert,Thomas J. Meyer,M. Kewenig,Carsten Dubs,Philipp Pirro,Andrii V. Chumak,Andrii V. Chumak +14 more
TL;DR: The emerging field of magnonics, which utilizes spin waves for data transport and processing, proposes a promis... as discussed by the authors, which is a promising field of research in computer science.
Journal ArticleDOI
A magnonic directional coupler for integrated magnonic half-adders.
Qi Wang,Qi Wang,M. Kewenig,Michael Schneider,Roman Verba,F. Kohl,Björn Heinz,Moritz Geilen,Morteza Mohseni,Bert Lägel,Florin Ciubotaru,Christoph Adelmann,Carsten Dubs,Sorin Cotofana,Oleksandr V. Dobrovolskiy,Thomas Brächer,Philipp Pirro,Andrii V. Chumak,Andrii V. Chumak +18 more
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.
