Ultrafast demagnetization in bulk nickel induced by X-ray photons tuned to Ni and absorption edges

Konrad J. Kapcia, Victor Tkachenko, Flavio Capotondi +4

Studies of light-induced demagnetization started with the experiment performed by Beaupaire et al. on nickel. Here, we present theoretical predictions for X-ray induced demagnetiza…

Photon shot-noise limited transient absorption soft X-ray spectroscopy at the European XFEL

Loïc Le Guyader, Andrea Eschenlohr, Martin Beye +61

Femtosecond transient soft X-ray Absorption Spectroscopy (XAS) is a very promising technique that can be employed at X-ray Free Electron Lasers (FELs) to investigate out-of-equilib…

Non-equilibrium self-assembly of spin-wave solitons in FePt nanoparticles

D. Turenne, A. Yaroslavtsev, X. Wang +36

Magnetic nanoparticles such as FePt in the L10-phase are the bedrock of our current data storage technology. As the grains become smaller to keep up with technological demands, the…

Ultrafast molecular orbital tomography of a pentacene thin film using time-resolved momentum microscopy at a free-electron laser

K. Baumgärtner, M. Reuner, C. Metzger +19

We use time-resolved momentum microscopy at a free-electron laser (FEL) and extend orbital tomography into the time domain to image the electronic wave functions of excited molecul…
