| Outline of Final Research Achievements |
Resonant x-ray diffraction provides us with a powerful tool to observe the orders of spin, orbital, charge in the strongly correlated electron system. The soft x-rays in a range from 500 eV to 1500 eV covers the L2,3 absorption edges of the 3d transition metals as well as the M5 absorption edges of 4f rare-earth metals. Thee resonant transition of these edges enables us to study the 3d or the 4f electronic states directly. We have been studying the spin and orbital states in the strongly correlated electron system. Especially, we used circularly polarized x-ray beam, which reveals the chirality of the spin and orbital orders . In this project, we have developed the focusing system with a fresnel zone plate. This system gives us an extremely focused beam of which size is about 200 nm in diameter. We will proceed the study of observation and control of spin and orbital chiral domains with external fields.
