Stimulated amplification of propagating spin waves
David Breitbach, Michael Schneider, Björn Heinz +13
Spin-wave amplification techniques are key to the realization of magnon-based computing concepts. We introduce a novel mechanism to amplify spin waves in magnonic nanostructures. U…
Stimulated-Raman-Adiabatic-Passage mechanism in a magnonic environment
Qi Wang, Thomas Brächer, Michael Fleischhauer +2
We discuss the realization of a magnonic version of the STImulated-Raman-Adiabatic-Passage (m-STIRAP) mechanism using micromagnetic simulations. We consider the propagation of magn…
Temperature dependence of spin pinning and spin-wave dispersion in nanoscopic ferromagnetic waveguides
Björn Heinz, Qi Wang, Roman Verba +10
The field of magnonics attracts significant attention due to the possibility of utilizing information coded into the spin-wave phase or amplitude to perform computation operations…
Propagating magnetic droplet solitons as moveable nanoscale spin-wave sources with tunable direction of emission
Morteza Mohseni, Qi Wang, Majid Mohseni +3
Magnetic droplets are strongly nonlinear and localized spin-wave solitons that can be formed in current-driven nanocontacts. Here, we propose a simple way to launch droplets in an…
Propagation of spin-waves packets in individual nano-sized yttrium iron garnet magnonic conduits
Björn Heinz, Thomas Brächer, Michael Schneider +10
Modern-days CMOS-based computation technology is reaching its fundamental limitations. The emerging field of magnonics, which utilizes spin waves for data transport and processing,…
Magnon-Fluxon interaction in a ferromagnet/superconductor heterostructure
O. V. Dobrovolskiy, R. Sachser, T. Brächer +7
Ferromagnetism and superconductivity are most fundamental phenomena in condensed matter physics. Entailing opposite spin orders, they share an important conceptual similarity: Dist…
