Inverse-design magnonic devices
Qi Wang, Andrii V. Chumak, Philipp Pirro
The field of magnonics offers a new type of low-power information processing, in which magnons, the quanta of spin waves, carry and process data instead of electrons. Many magnonic…
Nonlinear dynamics of topological ferromagnetic textures for frequency multiplication
Davi R. Rodrigues, Jonas Nothhelfer, Morteza Mohseni +3
We propose that the non-linear radio-frequency dynamics and nanoscale size of topological magnetic structures associated to their well-defined internal modes advocate for their use…
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…
A nonlinear magnonic nano-ring resonator
Qi Wang, Abbass Hamadeh, Roman Verba +5
The field of magnonics, which aims at using spin waves as carriers in data processing devices, has attracted increasing interest in recent years. We present and study micromagnetic…
Heisenberg Exchange and Dzyaloshinskii-Moriya Interaction in Ultrathin CoFeB Single and Multilayers
Tobias Böttcher, Kyujoon Lee, Frank Heussner +6
We present results of the analysis of Brillouin Light Scattering (BLS) measurements of spin waves performed on ultrathin single and multirepeat CoFeB layers with adjacent heavy met…
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…
