Phase-dependent parametric amplification of propagating spin waves in YIG nanostructures enabled by local inhomogeneities
Akira Lentfert, Ephraim Spindler, Björn Heinz +2
As magnonics evolves towards non-conventional computing, the development of phase-conserving and phase-sensitive amplification mechanisms becomes increasingly important. A particul…
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…
Ratchet motion of magnetic skyrmions driven by surface acoustic sawtooth waves
Philipp Schwenke, Ephraim Spindler, Vitaliy I. Vasyuchka +3
The manipulation of skyrmions by surface acoustic waves (SAW) has garnered significant interest in the field of spintronic devices. Previous studies established that skyrmions can…
Charge accumulation by Direct Magnetoelectric Effect in ScAlN/Ni Nanoscale Devices
Federica Luciano, Emma Van Meirvenne, Ephraim Spindler +6
This work investigates the direct magnetoelectric effect in thin-film lab scale composite heterostructures comprising a 100 nm thick piezoelectric Sc0.4Al0.6N (ScAlN) and a magneto…
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…
