Magnon-polaron control in a surface magnetoacoustic wave resonator
Kevin Künstle, Yannik Kunz, Tarek Moussa +6
Strong coupling between distinct quasiparticles in condensed matter systems gives rise to hybrid states with emergent properties. We demonstrate the hybridization of confined phono…
Efficient spin-wave excitation by surface acoustic waves in ultra-low damping YIG/ZnO-heterostructures
Yannik Kunz, Julian Schüler, Finlay Ryburn +7
We demonstrate the efficient excitation of spin waves in the ultra-low magnetic damping material yttrium-iron-garnet (YIG) by surface acoustic waves (SAWs). To this end, we employ…
Generation of gigahertz frequency surface acoustic waves in YIG/ZnO heterostructures
Finlay Ryburn, Kevin Künstle, Yangzhan Zhang +6
We study surface acoustic waves (SAWs) in yttrium iron garnet (YIG)/zinc oxide (ZnO) heterostructures, comparing the results of a computationally lightweight analytical model with…
Oscillatory Energy Exchange Between Waves Coupled by a Dynamic Artificial Crystal
Alexy D. Karenowska, Vasil S. Tiberkevich, Andrii V. Chumak +4
We describe a general mechanism of controllable energy exchange between waves propagating in a dynamic artificial crystal. We show that if a spatial periodicity is temporarily impo…
Magnonic crystal based forced dominant wavenumber selection in a spin-wave active ring
A. D. Karenowska, A. V. Chumak, A. A. Serga +2
Spontaneous excitation of the dominant mode in a spin-wave active ring -- a self-exciting positive-feedback system incorporating a spin-wave transmission structure -- occurs at a c…
