| Research Abstract |
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.
