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…
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…
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.…
