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…
Magnetic diffuse scattering in artificial kagome spin ice
Oles Sendetskyi, Luca Anghinolfi, Valerio Scagnoli +7
The study of magnetic correlations in dipolar-coupled nanomagnet systems with synchrotron x-ray scattering provides a means to uncover emergent phenomena and exotic phases, in part…
Coherence Properties of Individual Femtosecond Pulses of an X-ray Free-Electron Laser
I. A. Vartanyants, A. Singer, A. P. Mancuso +33
Measurements of the spatial and temporal coherence of single, femtosecond x-ray pulses generated by the first hard x-ray free-electron laser (FEL), the Linac Coherent Light Source…
