The electronic structure of A-site ordered perovskite CaCu 3 Ti 4 O 12 (CCTO) was studied by X-ray Raman scattering. Core-excitation of Cu 2p 3 d and 2p 4 p were observed under excitation around the Cu K absorption edge, where underlining denotes cor

We report an investigation on the mixed-valence state for $\mathrm{Yb}X{\mathrm{Cu}}_{4}$ compounds with $X$ = Mg, Cd, In, and Sn. The x-ray diffraction measurements on $X$ = Sn have revealed a cubic ${\mathrm{AuBe}}_{5}$-type structure with the latt

The electronic structures of YbCdCu4 and YbInCu4 have been studied by X-ray absorption spectroscopy at room tem- perature. We have observed a shoulder structure at 8940 eV on the low-energy side of the Yb3+ component in the Yb LIII-edge. This structu

Polarization-dependent Ti K X-ray absorption and Ti K α X-ray emission spectroscopy (XAS and XES) experiments have been carried out for single-crystalline Ti 2 O 3 with metal-insulator transition (MIT) around 450 K. Both the XAS and XES spectra exhi

Cesium manganese hexacyanoferrates exhibit an interesting phenomenon of temperature-induced phase transition accompanied by a variation in the magnetic susceptibility. We observed the variation in the electronic state of Mn during the phase transitio
