Abstract Multiferroic materials can host a plethora of intriguing phenomena due to the presence multiple ferroic properties that break both spatial inversion symmetry and time reversal at an observable scale. Hexagonal manganite multiferroics are particular interest as their symmetry-lowering phase transition be described by Mexican-hat-like potential energy surface. The early universe is proposed have undergone similar gives rise formation one-dimensional topologically protected defects...
Abstract The three-dimensional domain structure of ferroelectric materials significantly influences their properties. improper multiferroics, such as YMnO 3 , is driven by a non-ferroelectric order parameter, leading to unique hexagonal vortex patterns and topologically protected walls. Characterizing the these domains walls has been elusive, however, due lack suitable imaging techniques. Here, we present multi-peak Bragg coherent x-ray diffraction determination in single nanocrystals. We...
Abstract The exploration of multiferroic materials and their interaction with light at the nanoscale presents a captivating frontier in science. Bismuth Ferrite (BiFeO 3 , BFO), standout among these materials, exhibits room-temperature ferroelectric antiferromagnetic behaviour magnetoelectric coupling. Of particular interest is phenomenon photostriction, light-induced deformation crystal structures, which enhances prospect for device functionality based on materials. Understanding harnessing...
Abstract Although the LiCoO 2 (LCO) cathode material has been widely used in commercial lithium ion batteries (LIB) and shows high stability, LIB’s improvements have several challenges that still need to be overcome. In this paper, we studied in-operando structural properties of LCO within battery cells using Bragg Coherent X-ray Diffraction Imaging identify ways optimise batteries’ cycling. We successfully reconstructed scattering phase variation (a fingerprint atomic displacement) a ≈ (1.6...
Abstract The arrangement of atoms within a crystal and information on deviations from the ideal lattice is encoded in diffraction pattern obtained an appropriately conducted Bragg coherent imaging (BCDI) experiment.
