Nanoscale subsurface dynamics of solids upon high-intensity laser irradiation observed by femtosecond grazing-incidence x-ray scattering
Lisa Randolph, Mohammadreza Banjafar, Thomas R. Preston +28
Observing ultrafast laser-induced structural changes in nanoscale systems is essential for understanding the dynamics of intense light-matter interactions. For laser intensities on…
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…
