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

By calculation and analysis of the bare conduction bands in a large number of hole-doped
high-temperature superconductors, we have identified the range of the intralayer hopping as …

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 …

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 …

Cuprates have been at the center of long debate regarding their superconducting
mechanism; therefore, predicting the critical temperatures of cuprates remains elusive …

We have investigated the composition YSr 2 Cu 3-x M x O y and obtained the 123-structure
for M= Li, Al, Ti, V, Cr, Fe, Co, Ga, Ge, Mo, W and Re. Superconductivity is observed for the …

We report thesynthesis and characterization of Sr2YCu3_xMxOj,, M= Al, Pb, Fe, and Co,
analogues of the 92 K superconducting perovskite Ba2YCu307. While phase-pure …

The reaction product from an oxide mixture of 1Pb: 2Sr: 0.75 Y: 25Ca: 2Cu at 960° C was
nearly single phase. The crystal structure of a single crystal, selected from the reaction …

Many copper‐oxide‐based superconducting compounds have been synthesized in recent
years–currently more than 30 families are known, with superconducting transition …

For copper-based superconductors, the maximum superconducting transition temperature T
c, max of different families measured from experiment can vary from 38 K in La 2 CuO 4 to …
