Since the discovery of superconductivity above 30 K by Bednorz and Müller in the La copper
oxide system, the critical temperature has been raised to 90 K in Y Ba 2 Cu 3 O 7 and to 110 …

A comprehensive review of structure work on high-T c oxides as reported during the years
1987 and 1988 is given. Thirteen structures are refined from X-ray single-crystal and/or …

Studying the structure of disordered and partially ordered materials is notoriously difficult.
Recently, significant advances have been made using the atomic pair distribution function …

The crystal structures of the known copper oxide superconductors are described, with
particular emphasis on the manner in which they fall into structural families. The local charge …

Spectacular advances in superconductors have taken place in the past two years. The upper
temperature for superconductivity has risen from 23 K to 122 K, and there is reason to …

Deviations in atomic positions from those of the average crystallographic structure of
superconducting Tl 2 ba 2 CaCu 2 O 8 were studied by pair-distribution function (PDF) …

Pulsed neutron diffraction measurements on nano-scale powder of ceria, CeO2, uncovered
new structural features which appear to be intimately related to the function of this material …

抄録 Recent advances in the methods of structural analysis, in particular the use of particle
accellerators to produce pulsed neutrons and synchrotron radiation, have greatly improved …

The conventional X-ray diffraction (XRD) methods probe for the presence of long-range
order towards a solution of the average crystal structure. Experimentally, structural …

The electron density distribution and local structure of the high temperature thermoelectric
material Mg2Si have been studied and analyzed. Powder X-ray data of Mg2Si is analyzed in …
