9. Coherent Correlation Imaging for resolving fluctuating states of matter

Christopher Klose (Max Born Institute Berlin)

Oral

Fluctuations and stochastic processes are ubiquitous in nanometer-scale systems, especially in the presence of disorder. Real-space access to fluctuating states is impeded by a fundamental dilemma between spatial and temporal resolution. Averaging over an extended period of time (or repetitions) is key for the majority of high-resolution imaging experiments, especially in weak contrast...

42. Probing thermally activated dynamics in Artificial Spin Ices with coherent X-rays

Oier Bikondoa (Department of Physics - University of Warwick (UK) & XMaS UK CRG Beamline at the ESRF)

Oral

Arrays of nanoscaled magnetic elements, each acting as a single mesospin, are the building blocks of artificial systems of varying complexity in which the mesospin and lattice geometry can be used to design emergent mesoscale magnetic order. The geometry of the mesospin lattice determines the magnetic dimensionality and the interactions between the elements affect the global ordering and...

59. Piezoelectric response in PMN relaxor ferroelectric probed by in-situ wide-angle X-ray Photon Correlation Spectroscopy

Carol Thompson (Materials Science Division, Argonne National Laboratory / Department of Physics, Northern Illinois University)

Oral

The development of advanced functional materials relies on understanding interactions and heterogeneity at nanometer-to-micrometer length scales. The extraordinary electromechanical properties of relaxor ferroelectrics are widely attributed to the crucial role of spatial structural heterogeneity. Recent developments in coherent x-ray sources and methods significantly advance the possibilities...
