Excitation of the Gyrotropic Mode in a Magnetic Vortex by Time-Varying Strain
Vadym Iurchuk, Jürgen Lindner, Jürgen Fassbender +1
We demonstrate excitation of the gyrotropic mode in a magnetostrictive vortex by time-varying strain. The vortex dynamics is driven by a time-varying voltage applied to the piezoel…
Nontrivial Aharonov-Bohm effect and alternating dispersion of magnons in cone-state ferromagnetic rings
Vera Uzunova, Lukas Körber, Agapi Kavvadia +4
Soft magnetic dots in the form of thin rings have unique topological properties. They can be in a vortex state with no vortex core. Here, we study the magnon modes of such systems…
Piezostrain -- a local handle to control gyrotropic dynamics in magnetic vortices
Vadym Iurchuk, Serhii Sorokin, Jürgen Lindner +2
We present a study of the piezostrain-tunable gyrotropic dynamics in CoFeB vortex microstructures fabricated on a 0.7PMN-0.3PT single crystalline substrate. Us…
Modification of three-magnon splitting in a flexed magnetic vortex
Lukas Körber, Christopher Heins, Ivan Soldatov +4
We present an experimental and numerical study of three-magnon splitting in a micrometer-sized magnetic disk with the vortex state strongly deformed by static in-plane magnetic fie…
Finite-element dynamic-matrix approach for propagating spin waves: Extension to mono- and multilayers of arbitrary spacing and thickness
Lukas Körber, Alexander Hempel, Andreas Otto +4
In our recent work [AIP Adv. 11, 095006], we presented an efficient numerical method to compute dispersions and spatial mode profiles of spin waves propagating in waveguides with t…
Curvilinear spin-wave dynamics beyond the thin-shell approximation: Magnetic nanotubes as a case study
Lukas Körber, Roman Verba, Jorge A. Otálora +4
Surface curvature of magnetic systems can lead to many static and dynamic effects which are not present in flat systems of the same material. These emergent magnetochiral effects c…
Finite-element dynamic-matrix approach for spin-wave dispersions in magnonic waveguides with arbitrary cross section
Lukas Körber, Gwendolyn Quasebarth, Andreas Otto +1
We present a numerical approach to efficiently calculate spin-wave dispersions and spatial mode profiles in magnetic waveguides of arbitrarily shaped cross section with any non-col…
Spin-wave frequency combs
Tobias Hula, Katrin Schultheiss, Francisco José Trindade Goncalves +11
We experimentally demonstrate the generation of spin-wave frequency combs based on the nonlinear interaction of propagating spin waves in a microstructured waveguide. By means of t…
