Modeling of the micro-focused Brillouin light scattering spectra
OndÅej Wojewoda, Martin HrtoÅ, Michal Urbánek
Although micro-focused Brillouin light scattering (BLS) has been used for more than twenty years, it lacks a complete theoretical description. This complicates the analysis of expe…
Mie-enhanced micro-focused Brillouin light scattering with wavevector resolution
Jakub KrÄma, OndÅej Wojewoda, Martin HrtoÅ +4
Magnons, the quanta of spin waves, are magnetic excitations of matter spanning through the entire crystal's Brillouin zone and covering a wide range of frequencies ranging from sub…
Elimination of substrate-induced FMR linewidth broadening in the epitaxial system YIG-GGG by microstructuring
David Schmoll, Rostyslav O. Serha, Jaganandha Panda +4
Modern quantum technologies and hybrid quantum systems offer the opportunity to utilize magnons on the level of single excitations. Long lifetimes, low decoherence rates, and a str…
YIG/CoFeB bilayer magnonic diode
Noura Zenbaa, Khrystyna O. Levchenko, Jaganandha Panda +9
We demonstrate a magnonic diode based on a bilayer structure of Yttrium Iron Garnet (YIG) and Cobalt Iron Boron (CoFeB). The bilayer exhibits pronounced non-reciprocal spin-wave pr…
Damping Enhancement in YIG at Millikelvin Temperatures due to GGG Substrate
Rostyslav O. Serha, Andrey A. Voronov, David Schmoll +12
Quantum magnonics aims to exploit the quantum mechanical properties of magnons for nanoscale quantum information technologies. Ferrimagnetic yttrium iron garnet (YIG), which offers…
