| Outline of Final Research Achievements |
We have constructed an experimental system for resonant x-ray diffraction at very low temperatures with full polarization analysis, which is utilized for studies of various kinds of multipole ordered states of f-electron compounds. By fully utilizing this system, we have clarified microscopic mechanisms of octupole ordered phase in Ce0.7La0.3B6 and quadrupole ordered states of PrPd3S4, DyPd3S4 and CePd3S4. In addition, we successfully found that the unknown ordered state in SmRu4P12 is an field induced charge ordered state, as has recently been theoretically predicted.
