Journal ArticleDOI
ECHIDNA: a decade of high-resolution neutron powder diffraction at OPAL
Maxim Avdeev,James R. Hester +1 more
TL;DR: The ECHIDNA high-resolution neutron powder diffractometer at the OPAL research reactor in Australia produces high-quality data for a broad spectrum of crystal and magnetic structural studies.
Journal ArticleDOI
New Perovskite-Related Structure Family of Oxide-Ion Conducting Materials NdBaInO4
Kotaro Fujii,Yuichi Esaki,Kazuki Omoto,Masatomo Yashima,Akinori Hoshikawa,Toru Ishigaki,James R. Hester +6 more
TL;DR: NdBaInO4 is obtained from a 1:1:1 molar mixture of BaCO3, In2O3, and Nd2O4 by calcination and sintering.
Journal ArticleDOI
Synchrotron x-ray diffraction reexamination of the sequence of high-temperature phases in SrRuO 3
TL;DR: In this paper, it has been shown that the crystal structure of the orthorhombic in space group Pnma, at room temperature, changes by a continuous transition to a structure in Imma at about 685 K, then by a discontinuous transformation to tetragonal $I4/mcm$ at about 825 K, and finally, continuously, to cubic at near 950 K.
Journal ArticleDOI
Direct Synthesis of Chromium Perovskite Oxyhydride with a High Magnetic‐Transition Temperature
Cédric Tassel,Yoshihiro Goto,Yoshinori Kuno,James R. Hester,Mark Green,Yoji Kobayashi,Hiroshi Kageyama +6 more
TL;DR: A novel oxyhydride SrCrO2H directly synthesized by a high-pressure high-temperature method offers an effective strategy to tune octahedral tilting in perovskites and to improve physical and chemical properties through mixed anion chemistry.
Journal ArticleDOI
Superconductivity in BaTi2Sb2O with a d1 Square Lattice
Takeshi Yajima,Kousuke Nakano,Fumitaka Takeiri,Toshio Ono,Yuko Hosokoshi,Yoshitaka Matsushita,James R. Hester,Yoji Kobayashi,Hiroshi Kageyama +8 more
TL;DR: In this article, a two-dimensional oxyantimonide, BaTi 2 Sb 2 O, was presented, which showed a superconducting transition at 1.2 K, representing the first superconductivity in a system with Ti 3+ (d 1 ) in a square lattice.
