Research Abstract

We have performed the optical study under multi-extreme conditions using infrared microscope at the beamlines BL43IR in SPring-8 and BL6B in UVSOR, and at our laboratory. We have investigated the changes of electronic states for the strongly correlated electron systems such as PrFe4P12, PrRu4P12, LiV2O4, Ge, Ln2Ir2O7 (Ln=Nd, Sm), Sm2Mo2O7 under the highly controlled temperatures and pressures.
