Spatio-temporal migration of antiferromagnetic domain walls in Sr2IrO4
Ian Robinson, David Yang, Ross Harder +18
By laser pump-probe time-resolved coherent magnetic X-ray diffraction imaging, we have measured the migration velocity of antiferromagnetic domain walls in the Mott insulator Sr2Ir…

Ultrafast heat transfer in single palladium nanocrystals seen with an X-ray free-electron laser
David Yang, James Wrigley, Jack Griffiths +11
We report transient highly strained structural states in individual palladium (Pd) nanocrystals, electronically heated using an optical laser, which precede their uniform thermal e…

Unveiling Nano-scale Crystal Deformation using Coherent X-ray Dynamical Diffraction
Longlong Wu, David Yang, Wei Wang +5
Visualization of internal deformation fields in crystalline materials helps bridge the gap between theoretical models and practical applications. Applying Bragg coherent diffractio…
