Time-resolved absorption spectroscopy as well magnetic circular dichroism with circularly polarized soft X-rays (XAS and XMCD) are powerful tools to probe electronic dynamics in materials element- site-selectively. Employing these methods, groundbreaking results have been obtained for instance alloys, which helped fundamentally advance the field of ultrafast magnetization dynamics. At free electron laser facility FLASH key capabilities XAS XMCD experiments recently improved: In an upgrade,...

X-ray free-electron lasers (XFELs) as the world's brightest light sources provide ultrashort pulses with a duration typically in order of femtoseconds. Recently, they have approached and entered attosecond regime, which holds new promises for single-molecule imaging studying nonlinear ultrafast phenomena such localized electron dynamics. The technological evolution XFELs toward well-controllable precise metrology processes has been, however, hampered by diagnostic capabilities characterizing...
Attosecond X-ray pulses are the key to studying electron dynamics at their natural time scale involving specific electronic states. They promising build conceptual bridge between physical and chemical photo-reaction processes. Free-electron lasers have demonstrated capability of generating intense attosecond pulses. However, harnessing them for time-resolving experiments investigations nonlinear absorption mechanisms remains a cutting-edge challenge. We characterised with durations down...
