Specific Synchrotron Radiation Facilities Users Community (SpRUC)

This research group consists of researchers and student members aiming to elucidate the magnetic properties of functional magnetic materials, with a focus on spintronic devices and permanent magnets. Our research objectives include uncovering mechanisms underlying these materials’ magnetic properties and exploring fundamental studies on magnetic materials that could enable unique functionalities for future applications. Our primary experimental techniques are synchrotron-based nano-magnetic analysis using X-ray absorption (XAS) and X-ray magnetic circular dichroism (XMCD) spectroscopies.
Our group aims to improve our research results using SPring-8 and NanoTerasu. We mainly use our mailing list to share information about measurements and analysis, and to build collaborative research networks. Furthermore, regular meetings will be held to discuss proposals to introduce advanced instruments to beamlines, plan future beamline upgrades, and pursue research to create new fields in functional magnetic materials. To attract new users, members will actively disseminate information through various academic meetings and explore other methods.
X-ray absorption spectroscopy with variable X-ray polarization is a direct, powerful tool for revealing the magnetic origins of functional materials. XMCD provides element-specific insights into magnetic moments and electronic states, enabling sensitive, non-destructive analysis of thin films and nanostructures. At SPring-8, state-of-the-art soft- and hard-X-ray MCD stations are installed at BL25SU, BL23SU, and BL39XU. These beamlines are key research hubs for our group. The recently launched NanoTerasu BL13U will play an important role in future research and development.
Other magnetic analysis techniques using synchrotron X-rays, such as magnetic Compton scattering and resonant X-ray magnetic scattering, are widely used. While XMCD and related methods remain our primary experimental technique, we will explore complementary approaches. In collaboration with other SpRUC research groups focused on these methods, our group aims to achieve significant progress in the study of functional magnetic materials.
