|Coherent X-ray scattering has emerged as one of the leading tools to study microscopic fluctuations in materials. However, the time resolution for the so-called X-ray photon correlation spectroscopy (XPCS) is limited by coherence and acquisition, and at best a few microseconds. Using a pair of X-ray pulses generated by two individual excitation lasers at the free electron laser LCLS (SLAC National Accelerator Laboratory), we were able to probe fluctuations in magnetic Skyrmion phases on nanosecond time scales. This work was led by Joshua Turner (SLAC) and carried out in close collaboration with Eric Fullerton and Sunil Sinha (UCSD), and Sujoy Roy and Steve Kevan (LBNL).
