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 …

Hole-doped cuprate high temperature superconductors have ushered in the modern era of
high temperature superconductivity (HTS) and have continued to be at center stage in the …

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 …

Electronic-energy-level structures of the layered Cu oxide compounds are drawn within the
ionic model. Correlations between the level separations obtained and the superconducting …

A new superconducting phase has been identified during measurements of the pressure–
temperature–composition phase diagram of the pseudobinary system YBa2Cu3O6+ x–O2 …

Abstract The superconducting phase YBa2Cu4O8 ('124') differs from YBa2Cu3O7 ('123') in
having a double, instead of single, Cu–O chain running parallel to the b axis. It was first …

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 …

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 …

The effect of ambient oxygen pressure on the synthesis of epitaxial YBa2Cu3O7− x films on
(100) SrTiO3 substrates by post‐deposition annealing of amorphous precursor films was …

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 …
