Description
We employed a novel coherent X-ray technique that uses a split-and-delay line in a pump-double-probe experimental scheme to measure ultrafast domain fluctuations for the first time at an X-ray free electron laser. By accessing the speckle pattern of a resonant charge order peak in Fe$_{3}$O$_{4}$, we imaged electronic domain fluctuations with sub-picosecond temporal resolution. Here we also demonstrate how a standard time-resolved x-ray diffraction experiment in a pump-probe setup complements the coherent X-ray experiment by revealing how the average and local domain structures evolve in Fe$_{3}$O$_{4}$, offering a unique perspective on the ultrafast dynamics of the lattice structure and
electronic heterogeneities.
