Imaging charge density wave defects

We propose to image Charge density waves (CDW) defects in Chromium, the archetypal material of CDW, by Bragg Coherent Diffraction Imaging (BCDI) at a CDW satellite reflection, taking advantage of the new ESRF source. If successful, we will try to relate the CDW defects to structural defects by complementing the data with BCDI at main reflections, and further invetigate the spin flip transition, where anomalies have previously been seen at a CDW satellite reflection. While opening new perspectives for imaging electronic orders, this experiment will shed light on the coupling in Cr between the lattice, the CDWs and the magnetic order.
