Non-Equilibrium Multiplet Excitations probed by the Branching Ratio in X-ray Absorption Spectroscopy
Tim Amrhein, Beyza Salantur, Ralph Püttner +6
We show that ultrafast electronic multiplet transitions in terbium metal are manifested by changes in the relative spectral weight of the and X-ray absorption reso…
Magnon-mediated terahertz spin transport in metallic Gd|Pt stacks
Oliver Gueckstock, Tim Amrhein, Beatrice Andres +11
We study femtosecond spin transport in a Gd|Pt stack induced by a laser pulse. Remarkably, the dynamics of the spin current from Gd to Pt suggests that its dominant driving force i…
First experiments with ultrashort, circularly polarized soft X-ray pulses at FLASH2
S. Marotzke, D. Gupta, R. -P. Wang +23
Time-resolved absorption spectroscopy as well as magnetic circular dichroism with circularly polarized soft X-rays (XAS and XMCD) are powerful tools to probe electronic and magneti…
Femtosecond charge and spin dynamics in CoPt alloys
Martin Pavelka, Simon Marotzke, Ru-Pan Wang +19
The use of advanced X-ray sources plays a key role in the study of dynamic processes in magnetically ordered materials. The progress in X-ray free electron lasers enables the direc…
