Depth-resolved magnetization dynamics in Fe thin films after ultrafast laser excitation
Valentin Chardonnet, Marcel Hennes, Romain Jarrier +12
We performed time-resolved x-ray resonant magnetic reflectivity measurements on a laser-excited ferromagnetic Fe thin film to simultaneously probe the transient structural and magn…
Anisotropic skyrmion liquid phase
Daniel Schick, Tim Matthies, Thomas Mutschler +2
The nature of the melting transition in two-dimensional systems of particles has attracted considerable research attention since the development of Kosterlitz-Thouless-Halperin-Nel…
Soft-X-ray momentum microscopy of nonlinear magnon interactions below 100-nm wavelength
Steffen Wittrock, Christopher Klose, Salvatore Perna +10
Magnons are quantised collective excitations of long-range ordered spins. At nanometre wavelengths, exchange interactions increasingly govern their dynamics, giving rise to a large…
Spectroscopic probe of ultrafast magnetization dynamics in the extreme ultraviolet spectral range
Johanna Richter, Somnath Jana, Robert Behrends +6
The development of spectroscopic techniques in the extreme ultraviolet (XUV) spectral range has significantly advanced the understanding of ultrafast interactions in magnetic syste…
Laser-driven resonant soft-X-ray scattering for probing picosecond dynamics of nanometre-scale order
Leonid Lunin, Martin Borchert, Niklas Schneider +6
X-ray scattering has been an indispensable tool in advancing our understanding of matter, from the first evidence of the crystal lattice to recent discoveries of nuclei's fastest d…
Ultrafast X-ray sonography reveals the spatial heterogeneity of the laser-induced magneto-structural phase transition in FeRh
Maximilian Mattern, Angel Rodriguez-Fernandez, Roman Shayduk +13
Phase transitions are governed by both intrinsic and extrinsic heterogeneities, yet capturing their spatio-temporal dynamics remains a challenge. While ultrafast techniques track p…
