Research Activities

Elucidating Magnetic Structures and Electronic States in Magnetic Materials through Advanced Synchrotron Radiation Techniques

We aim to elucidate the magnetic structures and electronic states of materials for spintronic and magnetic quantum devices, in order to uncover the origins of their unique properties and emergent phenomena. In particular, we are developing advanced magnetic imaging instruments that exploit the high spatial coherence of soft X-rays generated at the synchrotron radiation facility NanoTerasu, enabling magnetic imaging with unprecedented spatial resolution. Furthermore, by combining these techniques with time-resolved measurements utilizing the high-repetition pulsed characteristics of soft X-rays, we are pioneering methods to visualize nanoscale magnetic structure dynamics. Our research extends to the visualization of antiferromagnetic materials such as altermagnets and multiferroics, as well as the investigation of electronic states in emergent quantum materials using resonant X-ray scattering. In addition, to overcome current measurement limitations, we are developing advanced measurement informatics techniques that integrate data science and artificial intelligence for synchrotron-based material research.
