| Research Abstract |
We have constructed an experiment system for resonant x-ray diffraction at very low temperatures down to 0. 5 K and in magnetic fields up to 8 T at the JAEA beamline BL22XU in Spring-8. Using this system, we can study various kinds of exotic ordering phenomena of spin-orbit degrees of freedom appearing at low temperatures in strongly correlated electron systems. We have performed experiments for three typical samples of Ce0. 7La0. 3B6, PrPd3S4, and DyPd3S4, and have observed multipole ordering phases of felectrons.
