Magnetic Coherent Diffraction Imaging with hard X

The purpose of the proposal is to develop a set of new techniques for magnetic imaging at the nanoscale. The techniques rely on the combination of Coherent Diffraction Imaging techniques (3D-CDI, Bragg CDI, ptychography) with magnetic scattering. While this has been done in the soft X-ray range at 3rd generation synchrotron sources to study 2D ferromagnetic materials, only the EBS provides sufficient brilliance to implement similar methods in the hard X-ray range. Using hard X-rays will allow extending the scientific scope to bulk ferromagnetic materials and to thin and bulk antiferromagnetic materials. The imaging techniques should be fully vectorial and have a resolution of ~50 nm and a field of view of a few microns. The project requires instrumental, methodological and numerical developments, which will be beneficial to the ESRF user community. The project is funded until June 2024 by the French research agency (ANR) and the CNRS, including 3 postdoc grants.
