Anisotropic wavevector-dependent damping of thickness-quantized magnons
Tamara Azevedo, Rostyslav O. Serha, Yannik Kunz +7
Magnon damping is a key factor governing spin-wave transport and nonlinear dynamics of multimode magnon systems. However, many descriptions rely on the assumption of an effective m…
Nonlinear frequency shift and bistability of magnon-polarons
Kevin Künstle, Matthias Wagner, Philipp Knaus +7
We investigate the nonlinear dynamics of strongly coupled surface acoustic waves (SAWs) and spin waves (SWs) in a magnetoacoustic resonator based on a YIG/ZnO heterostructure by co…
Enhancement of magnon flux toward a Bose-Einstein condensate
Franziska Kühn, Matthias R. Schweizer, Tamara Azevedo +5
We present a combined theoretical and experimental study of angle-dependent parametric pumping of magnons in Yttrium Iron Garnet films, with a focus on the mechanisms that transfer…
Spontaneous Emergence of Phase Coherence in a quasiparticle Bose-Einstein Condensate
Malte Koster, Matthias R. Schweizer, Timo Noack +6
Since their prediction by Einstein at the dawn of quantum mechanics, Bose-Einstein condensates (BECs), owing to their property to show quantum phenomena on macroscopic scales, are…
Local temperature control of magnon frequency and direction of supercurrents in a magnon Bose-Einstein condensate
Matthias R. Schweizer, Franziska Kühn, Victor S. L'vov +4
The creation of temperature variations in magnetization, and hence in the frequencies of the magnon spectrum in laser-heated regions of magnetic films, is an important method for s…
