In this study, the electronic structures of A-site layer-ordered double perovskite YBaCo2O6 and YBaCo2O5.3 epitaxial thin films were investigated by x-ray photoemission spectroscopy (PES), x-ray absorption spectroscopy (XAS), and x-ray magnetic ci...
Double-perovskite GdBaCo2O5.5 (GBCO) exhibits various fascinating features, including temperature- and magnetic-field-induced ferromagnetic to antiferromagnetic phase transition associated with the two ionic orders: an A-site Gd/Ba order along the...

We have synthesized polycrystalline samples of Eu2Pt6(Al1-xGax)(15 )(x = 0, 0.05. 0.1, 0.2, 0.3, and 1) and examined electrical resistivity, magnetic susceptibility, high-field magnetization, and X-ray absorption spectra at the Eu L-3-edge. With i...
Both the Jahn-Teller distortion of CuO octahedra and magnetic
ordering are absent in hexagonal BaCuSbO suggesting a Cu 3
spin-orbital liquid state. Here, by means of resonant x-ray scattering and
absorption experiment, we...
We have measured the lattice volume of ice VIII in different
pressure-temperature pathways and found isothermal compression at
low-temperature conditions makes the volume larger. Ice VIII has become its
high-pressure phase with the molar volume of...
The relationship between the magnetic interaction and photoinduced dynamics
in antiferromagnetic perovskites is investigated in this study. In
LaSrFeO thin films, commensurate spin ordering is
accompanied by charge disp...
