A Rate Model of Electron Populations for Non-linear High-Fluence X-ray Absorption Near-Edge Spectra
Robin Y. Engel, Markus Scholz, Jan O. Schunck +1
Absorbing a focused, femtosecond X-ray pulse from a Free-Electron Laser (FEL) can lead to extreme electronic excitations in solids. This excitation drives changes of the electronic…
Electron Dynamics at High-Energy Densities in Nickel from Non-linear Resonant X-ray Absorption Spectra
Robin Y. Engel, Oliver Alexander, Kaan Atak +40
The pulse intensity from X-ray free-electron lasers (FELs) can create extreme excitation densities in solids, entering the regime of non-linear X-ray-matter interactions. We show L…
Time-Resolved XUV absorption spectroscopy and magnetic circular dichroism at the Ni -edges
Marcel Hennes, Benedikt Rösner, Valentin Chardonnet +21
Ultrashort optical pulses can trigger a variety of non-equilibrium processes in magnetic thin films affecting electrons and spins on femtosecond timescales. In order to probe the c…
Simultaneous two-color snapshot view on ultrafast charge and spin dynamics in a Fe-Cu-Ni tri-layer
Benedikt Rösner, Boris Vodungbo, Valentin Chardonnet +19
Ultrafast phenomena on a femtosecond timescale are commonly examined by pump-probe experiments. This implies multiple measurements where the sample under investigation is pumped wi…
Structural dynamics during laser induced ultrafast demagnetization
Emmanuelle Jal, Victor López-Flores, Niko Pontius +6
The mechanism underlying femtosecond laser pulse induced ultrafast magnetization dynamics remains elusive despite two decades of intense research on this phenomenon. Most experimen…
