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…
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…
