Teruki Motohashi,Taira Takahashi,Makoto Kimura,Yuji Masubuchi,Shinichi Kikkawa,Yoshiki Kubota,Yoji Kobayashi,Hiroshi Kageyama,Masaki Takata,Susumu Kitagawa,Ryotaro Matsuda +10 more
TL;DR: In this paper, the double-perovskite type BaYMn2O5+δ was studied by high-temperature synchrotron X-ray diffraction (SXRD) under precisely controlled oxygen pressure to gain deeper understanding of the remarkable oxygen intake/release capability of this oxide.

R. Murata,T. Sato,Tetsuji Okuda,Y. Horibe,H. Tsukasaki,Shigeo Mori,N. Yamaguchi,Kunihisa Sugimoto,Shogo Kawaguchi,Masaki Takata,Takuro Katsufuji +10 more
TL;DR: In this article, the physical properties of hollandite titanates with double chains of edge-sharing octahedra with $d$ electrons in the 2g states were studied and it was shown that there is an electronic phase transition at $\ensuremath{\sim}220$ K at which various properties exhibit anomalies.
Journal ArticleDOI
Electron Charge Density Study of (Na1-xKx)NbO3 in Cubic Structure
Chikako Moriyoshi,Jun Ichi Kato,Yoshihiro Terado,Satoshi Wada,Masaki Takata,Yoshihiro Kuroiwa +5 more
TL;DR: In this article, the exact analysis using the maximum entropy method (MEM)/Rietveld method demonstrates that the covalent bonding is formed on the Nb-O bond whereas the Na/K atoms are ionic in the entire composition range.
