Nanosecond X-Ray Photon Correlation Spectroscopy on Magnetic Skyrmions [PDF]
Physical Review Letters, 2017 We report an x-ray photon correlation spectroscopy method that exploits the recent development of the two-pulse mode at the Linac Coherent Light Source. By using coherent resonant x-ray magnetic scattering, we studied spontaneous fluctuations on nanosecond time scales in thin films of multilayered Fe/Gd that exhibit ordered stripe and Skyrmion lattice ...
