A variety of synthetic strategies has been employed to prepare pure monophasic cuprates of
different families with good superconducting properties. Besides the traditional ceramic …

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 …

Copper oxide superconductors possess multi-layered structures with a layer sequence of-
CuO 2-(Q-CuO 2) n-1-AO-(MO 1±) m-AO-or-CuO 2-B-(O 2-B) s-1-CuO 2-AO-(MO 1±) m-AO …

THE'infinite-layer'parent structure1 of the copper oxide superconductors (Fig. 1) is the
simplest structure containing the CuO2 sheets that are apparently essential to high-transition …

A new homologous series of high-pressure phases, Sr n− 1 Cu n+ 1 O 2n (n= 3, 5,…), were
found in the SrO CuO system treated at 6 GPa and 1373–1573 K. These crystallize in …

Analysis of the many experiments on high-temperature superconductivity indicate several
essential aspects of any theory. The conductivity and other transport properties as a function …

Most of the known cuprate superconductors are shown to belong structurally to a single
family and are closely related to each other. The relationships between the structures of …

Superconductivity was observed at 117 K in the Ba Ca Cu O samples synthesized at
950° C under 5.0 GPa for 1 h. The samples were multiphase. Electrical resistivity and DC …

High-pressure methods have been used to synthesize multiphase compositions in the Hg
12 {n− 1} n homologous series. The phase assemblages were examined by optical, electron …

We review concepts and effects of electron correlations in the copper-oxide
superconductors. The purpose of this article is twofold. First, we provide an overview of …
