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…

Controlling the nonlinear relaxation of quantized propagating magnons in nanodevices
M. Mohseni, Q. Wang, B. Heinz +7
Relaxation of linear magnetization dynamics is well described by the viscous Gilbert damping processes. However, for strong excitations, nonlinear damping processes such as the dec…
