We have succeeded in X-ray-diffraction,-absorption spectroscopy,-magnetic circular dichroism,-resonant diffraction and neutron diffraction in 40-50 T. It enables us to investigate electronic-magnetic state of a correlated localized-itinerant electron system in ultra-strong magnetic field. It leads the opening of new research area: high magnetic field quantum beam science. The priority of Japan initiative in this area has been established among world quantum beam research facilities.

我们在40-50 t范围内成功地进行了x射线衍射、吸收光谱、磁圆二色性、共振衍射和中子衍射，使我们能够在超强磁场中研究相关的局部流动电子系统的电磁状态。它引领了高磁场量子束科学这一新的研究领域的开启。在世界量子束研究机构中，日本在这一领域的优先地位已经确立。
