Correlative analysis of structure and chemistry of LixFePO4 platelets using 4D-STEM and X-ray ptychography
L. A. Hughes, Benjamin H. Savitzky, Haitao D. Deng +9
Lithium iron phosphate (LixFePO4), a cathode material used in rechargeable Li-ion batteries, phase separates upon de/lithiation under equilibrium. The interfacial structure and che…
Direct observation of 3D topological spin textures and their interactions using soft x-ray vector ptychography
Arjun Rana, Chen-Ting Liao, Ezio Iacocca +21
Magnetic topological defects are energetically stable spin configurations characterized by symmetry breaking. Vortices and skyrmions are two well-known examples of 2D spin textures…
Differential electron yield imaging with STXM
William A. Hubbard, Jared J. Lodico, Xin Yi Ling +4
Total electron yield (TEY) imaging is an established scanning transmission X-ray microscopy (STXM) technique that gives varying contrast based on a sample's geometry, elemental com…
X-ray linear dichroic ptychography
Yuan Hung Lo, Jihan Zhou, Arjun Rana +11
Biominerals such as seashells, corals skeletons, bone, and enamel are optically anisotropic crystalline materials with unique nano- and micro-scale organization that translates int…
Advanced Denoising for X-ray Ptychography
Huibin Chang, Pablo Enfedaque, Jie Zhang +7
The success of ptychographic imaging experiments strongly depends on achieving high signal-to-noise ratio. This is particularly important in nanoscale imaging experiments when diff…
Universal criterion and phase diagram for switching a magnetic vortex core in soft magnetic nanodots
Ki-Suk Lee, Sang-Koog Kim, Young-Sang Yu +4
The universal criterion for ultrafast vortex-core switching between the up- and down-core bistates in soft magnetic nanodots was investigated by micromagnetic simulations along wit…
