FEMTOSPEX-DynaMax
Ultrafast XAS, XMCD, XMRS, and RXD with femtosecond soft x-ray pulses at UE56-1-ZPM
The FemtoSpeX-DynaMaX is a fix end-station installed at the UE56-1-ZPM beamline. Using ultrashort x-ray pulses with variable polarization from the femtoslicing source at the UE56-1-ZPM beamline and intrinsically synchronized laser pulses from a Ti:Sa laser amplifier system it is dedicated to ultrafast XAS, XMCD, (magnetic) reflectivity and soft x-ray diffraction experiments. The sample environment includes LHe cooling, and applying magnetic fields up to 1.5 T by a fast-ramping super-conducting vector magnet. The main scientific focus is on ultrafast magnetization dynamics.
Selected Applications:- investigating ultrafast phase transition in strongly correlated materials with the focus on ultrafast magnetic dynamics
- probing magnetic materials element selectively
- L2,3 absorption edges of the 3d transition metals
- M4,5 resonances of 4f rare earth elements
