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 magnetic and struct…
Ultrafast Opto-magnetic Effects in the Extreme Ultraviolet Spectral Range
Martin Hennecke, Clemens von Korff Schmising, Kelvin Yao +20
Coherent light-matter interactions mediated by opto-magnetic phenomena like the inverse Faraday effect (IFE) are expected to provide a non-thermal pathway for ultrafast manipulatio…
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…
Ultrafast time-evolution of chiral Néel magnetic domain walls probed by circular dichroism in x-ray resonant magnetic scattering
Cyril Léveillé, Erick Burgos-Parra, Yanis Sassi +18
Non-collinear spin textures in ferromagnetic ultrathin films are attracting a renewed interest fueled by possible fine engineering of several magnetic interactions, notably the int…
Laser-induced ultrafast demagnetization and perpendicular magnetic anisotropy reduction in a CoTb thin film with stripe domains
M. Hennes, A. Merhe, X. Liu +15
We use time-resolved x-ray resonant magnetic scattering (tr-XRMS) at the Co M- and Tb O-edges to study ultrafast demagnetization in an amorphous CoTb allo…
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…
High-fidelity phase and amplitude control of phase-only computer generated holograms using conjugate gradient minimisation
D. Bowman, T. L. Harte, V. Chardonnet +7
We demonstrate simultaneous control of both the phase and amplitude of light using a conjugate gradient minimisation-based hologram calculation technique and a single phase-only sp…
