| Abstract Scope |
Ferroic materials and mechanisms of enhancement of their properties are actively studied due to large potential for their applications in spintronic devices, solar cell technologies, reconfigurable electronics, catalysts, and energy and information storage. Topological approach proved itself useful in explaining this materials behavior at lower dimension where exotic configurations of ferroic order (such as vortices, skyrmiones, hedges etc) are observed.
Improvements in coherence at 3rd and 4th generation light sources, phase-retrieval algorithms, instruments and optics, theoretical modeling and predictive behavior of materials, and machine learning tools bridging experiment to models have allowed the shift towards quantitative and qualitative spatial mapping of topological phases in ferroic materials.
In this talk we shall introduce Bragg coherent diffractive imaging as a state of the art technique in consort with Landau theory to probe emergent topological phases in perovskite nanostructure during field induced structural phase transitions. |
