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…
Optical control of 4f orbital state in rare-earth metals
N. Thielemann-Kühn, T. Amrhein, W. Bronsch +28
A change of orbital state alters the coupling between ions and their surroundings drastically. Orbital excitations are hence key to understand and control interaction of ions. Rare…
Ultrafast and Energy-Efficient Quenching of Spin Order: Antiferromagnetism Beats Ferromagnetism
Nele Thielemann-Kühn, Daniel Schick, Niko Pontius +6
By comparing femtosecond laser pulse induced ferro- and antiferromagnetic dynamics in one and the same material - metallic dysprosium - we show both to behave fundamentally differe…
Itinerant and localized magnetization dynamics in antiferromagnetic Ho
L. Rettig, C. Dornes, N. Thielemann-Kuehn +12
Using femtosecond time-resolved resonant magnetic x-ray diffraction at the Ho L3 absorption edge, we investigate the demagnetization dynamics in antiferromagnetically ordered metal…
