| Research Abstract |
In strongly correlated electron systems, we have sometimes observed novel ordering states of localized (d or f) and itinerant (p) electrons due to the effect of orbital hybridization. In this study we have observed the orderings of electron degrees of freedom for itinerant electrons as well as localized electrons in some transition metal compounds by using synchrotron X-ray, soft X-ray and neutron diffraction/scattering techniques under a high pressure or a strong magnetic field. From these observations we have elucidated the generating mechanism of the orderings. In particular, diffractometers (spectrometers) with superconducting magnet for resonant soft X-ray scattering were developed for this purpose.
