強磁場Ｘ線分光 強度の極めて高い放射光と強磁場を組み合わせた強磁場Ｘ線散乱、強磁場Ｘ線分光は物質の磁性と電子構造を探る新しい手法として発展が期待されています。 簡便使えるミニコイルと精度の高い実験が可能な 長時間パルス磁場を併用して、Ｘ線内殻吸収、MCD、共鳴散乱など強磁場中で電子構造と磁気状態を解明できる新手法を開発し、それらを用いた研究を推進しています。 X-ray Spectroscopy in High Magnetic Fields X-ray Spectroscopy in High Magnetic Fields is a novel tool to investigate magnetic and electronic states of matters in extreme conditions. We have developed a portable mini coil system for wide applications and a long pulse coil system for high precision measurements. These devices are used to study varieties of magnetic systems by combining with XAS, XMCD, resonant scattering and diffraction.
