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…
Vision Transformer for Multi-Domain Phase Retrieval in Coherent Diffraction Imaging
Jialun Liu, David Yang, Ian Robinson
Bragg coherent diffraction imaging (BCDI) phase retrieval becomes rapidly difficult in the strong-phase regime, where a crystal contains distortions beyond half a lattice spacing.…
Symmetry Breaking during Low-Temperature Domain Formation in Micron-sized Magnetite Crystals
Yue Dong, David Yang, Jialun Liu +3
We report the results of synchrotron Bragg Coherent X-ray Diffraction Imaging (BCDI) experiments to investigate domain formation in a micron-sized magnetite crystal undergoing the…
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…
