Enhanced thermally-activated skyrmion diffusion with tunable effective gyrotropic force
Takaaki Dohi, Markus Weißenhofer, Nico Kerber +12
Magnetic skyrmions, topologically-stabilized spin textures that emerge in magnetic systems, have garnered considerable interest due to a variety of electromagnetic responses that a…
Megahertz-rate Ultrafast X-ray Scattering and Holographic Imaging at the European XFEL
Nanna Zhou Hagström, Michael Schneider, Nico Kerber +97
The advent of X-ray free-electron lasers (XFELs) has revolutionized fundamental science, from atomic to condensed matter physics, from chemistry to biology, giving researchers acce…
Skyrmion pinning energetics in thin film systems
Raphael Gruber, Jakub Zázvorka, Maarten A. Brems +7
A key issue for skyrmion dynamics and devices are pinning effects present in real systems. While posing a challenge for the realization of conventional skyrmionics devices, exploit…
Constructing coarse-grained skyrmion potentials from experimental data with Iterative Boltzmann Inversion
Yuqing Ge, Jan Rothörl, Maarten A. Brems +5
In an effort to understand skyrmion behavior on a coarse-grained level, skyrmions are often described as 2D quasi particles evolving according to the Thiele equation. Interaction p…
Direct imaging of chiral domain walls and Néel-type skyrmionium in ferrimagnetic alloys
Boris Seng, Daniel Schönke, Javier Yeste +15
The evolution of chiral spin structures is studied in ferrimagnet Ta/Ir/Fe/GdFeCo/Pt multilayers as a function of temperature using scanning electron microscopy with polarization a…
Probing topological spin structures using light-polarization and magnetic microscopy
Till Lenz, Georgios Chatzidrosos, Zhiyuan Wang +12
We present an imaging modality that enables detection of magnetic moments and their resulting stray magnetic fields. We use wide-field magnetic imaging that employs a diamond-based…
Commensurability between element symmetry and the number of skyrmions governing skyrmion diffusion in confined geometries
Chengkun Song, Nico Kerber, Jan Rothörl +10
Magnetic skyrmions are topological magnetic structures, which exhibit quasi-particle properties and can show enhanced stability against perturbation from thermal noise. Recently, t…
Anisotropic skyrmion diffusion controlled by field-induced symmetry breaking
Nico Kerber, Markus Weißenhofer, Klaus Raab +4
Diffusion of particles has wide repercussions ranging from particle-based soft matter systems to solid state systems with particular electronic properties. Recently, in the field o…
Skyrmion Lattice Phases in Thin Film Multilayer
Jakub Zázvorka, Florian Dittrich, Yuquing Ge +7
Phases of matter are ubiquitous with everyday examples including solids and liquids. In reduced dimensions, particular phases, such as the two-dimensional (2D) hexatic phase and co…
Faster chiral versus collinear magnetic order recovery after optical excitation revealed by femtosecond XUV scattering
Nico Kerber, Dmitriy Ksenzov, Frank Freimuth +11
While chiral spin structures stabilized by Dzyaloshinskii-Moriya interaction (DMI) are candidates as novel information carriers, their dynamics on the fs-ps timescale is little kno…
Asymmetric skyrmion Hall effect in systems with a hybrid Dzyaloshinskii-Moriya interaction
Kyoung-Whan Kim, Kyoung-Woong Moon, Nico Kerber +2
We examine the current-induced dynamics of a skyrmion that is subject to both structural and bulk inversion asymmetry. There arises a hybrid type of Dzyaloshinskii-Moriya interacti…
