k-Selective Electrical-to-Magnon Transduction with Realistic Field-distributed Nanoantennas
Andreas Höfinger, Andrey A. Voronov, David Schmoll +9
The excitation and detection of propagating spin waves with lithographed nanoantennas underpin both classical magnonic circuits and emerging quantum technologies. Here, we establis…
Long-range propagating paramagnon-polaritons in organic free radicals
Sebastian Knauer, Roman Verba, Rostyslav O. Serha +5
Materials are commonly distinguished by their magnetic response into diamagnetic, paramagnetic, and magnetically ordered (ferro-, ferri-, and antiferromagnetic) phases. Diamagnets…
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…
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…
Wavenumber-dependent magnetic losses in YIG-GGG heterostructures at millikelvin temperatures
David Schmoll, Andrey A. Voronov, Rostslav O. Serha +7
Magnons have inspired potential applications in modern quantum technologies and hybrid quantum systems due to their intrinsic nonlinearity, nanoscale scalability, and a unique set…
