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…
Low temperature state in strontium titanate microcrystals using in situ multi-reflection Bragg coherent X-ray diffraction imaging
David Yang, Ana F. Suzana, Longlong Wu +12
Strontium titanate is a classic quantum paraelectric oxide material that has been widely studied in bulk and thin films. It exhibits a well-known cubic-to-tetragonal antiferrodisto…
