Abstract

The interplay between the charge-density wave (CDW), the spin-density wave (SDW), and the defect ordering in complex materials is under an intense discussion. There is a strong interest in how the competition between these striped orders plays a role in the promotion of the material’s functionality at the macroscopic scale. Up to now, only few works point the attention to the direct visualization of how SDW, CDW, and defects are organized in the materials. Here, we propose the use of an innovative technique that combines the sensitivity of resonant X-ray scattering (SXR) with the spatial resolution of scanning micro X-ray diffraction (μXRD), allowing the investigation of the spatial organization of the resonant magnetic and charge order. Recent results on nickelates, cobaltites, and cuprates demonstrate the presence of a nanoscale phase separation scenario where these multiple striped orders get self-organized and form competing granular networks of nanodomains.
