○ Abstract: Quantum materials originated from electron-electron correlation have been intensively investigated due to their scientific interests. Many researchers have tried to search for new insight and intriguing material systems, e.g., antiferromagnet-based spintronics. However, understanding of the physical properties of some model systems is yet incomplete due to experimental limitations, specifically hard X-ray-based scattering techniques. For instance,
Here, we introduce our experimental approach, resonant magnetic x-ray diffraction combined with full-field microscopy [1]. Using the techniques, we will systematically investigate emergent properties of quantum materials, e.g., ruthenate and iridate. Our studies also offer a comprehensive understanding based on the theoretical calculations combined with advanced hard x-ray scattering techniques. Moreover, we were able to visualize structural and (anti)ferromagnetic domains of thin films and single crystals. We propose that the techniques combined with electric field can explore and create new phases and emergent physical properties.
