The purpose of this research project is to establish a new method that clarifies the relation between the ordering state and the novel physical property, focusing on the observation of spin, orbital, and structural motifs appeared in the new functional materials. For this purpose, we have introduced a polarization analysis apparatus, a superconducting magnet, and a pulse magnet in our soft x-ray diffractometer. In a consequence, we have successfully observed orbital ordering states and spin chiral ordering states appeared in several multiferroic materials. This innovation has been realized for the first time in the world.

本研究项目的目的是建立一种新的方法来阐明有序状态与新的物理性质之间的关系，重点是观察新功能材料中出现的自旋、轨道和结构基元。为此，我们在软X射线衍射仪中引入了极化分析装置、超导磁体和脉冲磁体。因此，我们成功地观察到了几种多铁材料中出现的轨道有序态和自旋手征有序态。这一创新在世界上是第一次实现。
