The 90 K superconductor, YBa2Cu3Oδ (YBCO), has proved to be highly adaptable
chemically as it can accommodate a wide variety of cationic and anionic substitutions …

The discovery of 30-K superconductivity in the La–Ba–Cu–O system1 and 90-K
superconductivity in the Y–Ba–Cu–O system2 stimulated a worldwide search for even …

This is a revised version of the first edition published in 1991. At the same time, this is a
revised version of the Syokabo edition, which was written in Japanese and published in …

The initial discovery by Bednorz and Muller1 of 35-K superconduc-tivity in the La–Ba–Cu–O
system has stimulated worldwide activity in searching for higher-temperature …

Oxide double perovskites A 2 B′ B′′ O 6 are a class of emerging materials in the fields of
optoelectronics and catalysis. Due to the chemical flexibilities of perovskite structures, there …

Structural, magnetic and electronic properties of compounds in the series R Ba 2 Cu 3 O 7−
x (R= Nd, Sm,..., and Lu) were studied. Resistivity, Meissner-effect, and shielding …

Perovskite will play an important role in the materials study to investigate the different
properties. The CASTEP (Cambridge Serial Total Energy Package) code will be used to …

Stable and reproducible superconductivity has been unambiguously observed in a new Tl-
Ba-Cu-O system containing no group-IIIB elements. Resistance in these rare-earth–free …

By reacting CuSatnOH (CuSatnOH=[/V-(3-aminopropyl) salicylaldiminato] hydroxocopper
(ll)) with rare-earth hexafluoro-acetylacetonates (hfac), complexes of general formula Ln …

A model for interpretation of x-ray-absorption near-edge structure (XANES) in transition-
metal compounds is presented based on λ= R backscattering from nearby atoms. The model …
