Abstract
We report on single-pulse resonant magnetic scattering experiments using soft x-ray pulses generated by the free-electron laser FLASH at DESY. We could record a magnetic diffraction pattern from a Co/Pt multilayer sample at the edge with a single 30-fs-long FEL pulse. The analysis of the magnetic small-angle scattering signal for subsequent pulses indicates a threshold energy density below which there is no indication that the magnetic properties of the sample might be altered.

Ultrafast probes for ultrasmall magnets
Published 1 March 2010
A single -femtosecond pulse has been used to observe x-ray diffraction of a magnetic material, potentially opening the way to ultrafast probing of spin dynamics with nanometer spatial resolution.
