Possible high Tc superconductivity in the Ba-La-Cu-O system
TL;DR: In this paper, Ba−La−Cu−O system, with the composition BaxLa5−xCu5O5(3−y) have been prepared in polycrystalline form, and samples with x=1 and 0.75,y>0, annealed below 900°C under reducing conditions, consist of three phases, one of them a perovskite-like mixed-valent copper compound.

The resonating valence bond state in La2CuO4 and superconductivity
TL;DR: The oxide superconductors, particularly those recently discovered that are based on La2CuO4, have a set of peculiarities that suggest a common, unique mechanism: they tend in every case to occur near a metal-insulator transition into an odd-electron insulator with peculiar magnetic properties.

The perovskite structure—a review of its role in ceramic science and technology
TL;DR: In this paper, the perovskite structure is used to illustrate the relationship of structure to composition, and the history of the fundamental science of structure-to-composition is described.
Journal ArticleDOI
Electronic structure of the high-temperature oxide superconductors
TL;DR: In this paper, a review of the results of the density-functional type of electronic structure calculations is presented, and their results are compared with the relevant experimental data, showing that the important electronic states are dominated by the copper and oxygen orbitals, with strong hybridization between them.

Superconductivity near 30 K without copper: the Ba 0.6 K 0.4 BiO 3 perovskite
Robert J. Cava,Bertram Batlogg,J. J. Krajewski,Reginald C. Farrow,L. W. Rupp,Alice E. White,K. T. Short,W. F. Peck,T. Kometani +8 more
TL;DR: The single-phase perovskite Ba0.6K0.4BiO3 has a magnetically determined onset temperature of 29.8 K, a Tc considerably higher than that of conventional superconductors and surpassed only by copper-containing compounds.

Über Alkali- und Erdalkalioxobismutate(V)†
TL;DR: In this article, the most basic compound being obtained is Ba7(BiO6)2, i.e., BaO/Bi2O3 mixtures, complete oxidation to Bi(V) at 950-1000°C is only achieved if BaO:Bi2o3 ≥ 5:1.
