Ultrafast XAS, XMCD, XMRS, and RXD with femtosecond soft x-ray pulses /UE56-1_ZPM

Using ultrashort x-ray pulses with variable polarization and intrinsically synchronized laser pulses from a Ti:Sa laser amplifier system, the instrument FemtoSpeX-DynaMaX at the UE56-1-ZPM beamline is dedicated to ultrafast XAS, XMCD, (magnetic) reflectivity and soft x-ray diffraction experiments. The sample environment includes LHe cooling, and 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
