Invited speaker

Bragg ptychography is a phase retrieval method combining crystalline sensitivity and the possibility to image extended 3D samples [God2011, Mas2017]. Recent progresses in Bragg ptychography formalism, namely, the introduction of the back projection operator [Hru2017] and the advent of 4th generation synchrotron sources have enabled the use of 3D Bragg ptychography with unprecedented accuracy,...

Ptychography is a scanning coherent diffraction imaging technique capable of simultaneous imaging of extended samples and beam characterization with diffraction-limited resolution. It is well developed at synchrotrons, but its scanning nature prevents its use for single-shot imaging at wide applications on FEL facilities.

Single-shot ptychography can be performed by collecting the...

34. High resolution spin texture imaging in spin caloritronics prototype device structures: New opportunities for coherent hard X-rays with resonant scattering at 4th generation light sources.

Oral

Spin caloritronics are currently a science focus due to their potential exploitation in the next generation of spintronics applications. This class of materials combine both spintronic and thermoelectric functionalities by interconversion of charge, spin and heat currents [1]. Revealing how atomic strain and magnetic structure are intertwined at the nanoscale is of central importance to the...
