Parametric Excitation and Instabilities of Spin Waves driven by Surface Acoustic Waves
Moritz Geilen, Roman Verba, Alexandra Nicoloiu +10
The parametric excitation of spin waves by coherent surface acoustic waves is demonstrated experimentally in metallic magnetic thin film structures. The involved magnon modes are a…
Room And Cryogenic Temperature Behaviour of Magnetic Sensors Based on Gan/Si Single Saw Resonators
Alexandra Nicoloiu, Florin Ciubotaru, Claudia Nastase +6
This work analyzes resonance frequency shift vs. the applied magnetic field strength for GHz operating GaN/Si SAW single resonators. Magnetostrictive elements (Ni and CoFeB) were d…
Fully Resonant Magneto-elastic Spin-wave Excitation by Surface Acoustic Waves under Conservation of Energy and Linear Momentum
Moritz Geilen, Alexandra Nicoloiu, Daniele Narducci +8
We report on the resonant excitation of spin waves in micro-structured magnetic thin films by surface acoustic waves (SAWs). The spin waves as well as the acoustic waves are studie…
Interference of co-propagating Rayleigh and Sezawa waves observed with micro-focussed Brillouin Light Scattering Spectroscopy
Moritz Geilen, Felix Kohl, Alexandra Stefanescu +3
We use micro-focussed Brillouin light scattering spectroscopy (BLS) to investigate surface acoustic waves (SAWs) in a GaN layer on a Si substrate at GHz frequencies. Furthermore…
