Double-pulse control of all optical magnetization reversal in Tb/Co multilayers
Sheng Li, Dinar Khusyainov, Rein Liefferink +7
Recent experiments have shown that femtosecond laser pulse with a Gaussian intensity profile can induce magnetization reversal in Tb/Co multilayers with a ring-shaped switching pat…
A fluctuation-free pathway for a topological magnetic phase transition
Riccardo Battistelli, Lukas Körber, Kai Litzius +27
Topological magnetic textures are particle-like spin configurations stabilized by competing interactions. Their formation is commonly attributed to fluctuation-driven, first-order…
Spin-correlation dynamics: A semiclassical framework for nonlinear quantum magnetism
Lukas Körber, Pim Coenders, Johan H. Mentink
Classical nonlinear theories are highly successful in describing far-from-equilibrium dynamics of magnets, encompassing phenomena such as parametric resonance, ultrafast switching,…
Coherent control of Floquet-engineered magnon frequency combs
Christopher Heins, Amelie L. Fehrmann, Lukas Körber +5
Frequency combs represent a hallmark of coherence emerging from nonlinear dynamics, where periodic driving organizes energy into a precisely spaced spectral structure. Extending th…
Effective Theory of Ultrafast Skyrmion Nucleation
Rein Liefferink, Lukas Körber, Kathinka Gerlinger +3
Laser-induced ultrafast skyrmion nucleation has been experimentally demonstrated in several materials. So far, atomistic models have been used to corroborate experimental results.…
Toroidal Moments in Confined Nanomagnets and their Impact on Magnonics
Felipe Brevis, Lukas Körber, B. Mimica-Figari +3
The nonreciprocity created by dipolar coupling, electric currents, and Dzyaloshinskii-Moriya interactions is discussed in cases where the magnon propagation direction has a compone…
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…
Nonlinear magnon control of atomic spin defects in scalable quantum devices
Mauricio Bejarano, Francisco J. T. Goncalves, Toni Hache +10
Ongoing efforts in quantum engineering have recently focused on integrating magnonics into hybrid quantum architectures for novel functionalities. While hybrid magnon-quantum spin…
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…
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…
Non-reciprocity of spin waves in magnetic nanotubes with helical equilibrium magnetization
Monica M. Salazar-Cardona, Lukas Körber, Helmut Schultheiss +5
Spin waves (SWs) in magnetic nanotubes have shown interesting nonreciprocal properties in their dispersion relation, group velocity, frequency linewidth and attenuation lengths. Th…
