✦ Synopsis

Structural and superconducting properties of La~ _xPrSr~CuO4 have been investigated. Substitution of Sr for La in LaPrCuO4 (T'-structure), induces a transformation to the T-structure unlike in LaSmCuO4 and LaGdCuOa where a transformation takes place from the T'-to the T*-structure. The transformation gets completed at x = 0.2. These studies suggest that the rare earth ionic size is critical in the T' ~ T (T*) transition. Superconductivity is observed in samples with 0.1 < x_< 0.25.

The phase diagram of the Lal.s\_xSmxSro.2CuO 4 system has been investigated by solid state reaction at 1150°C in an oxygen flow. In these conditions, two phases have been found: (i) T-phase which exhibits a homogeneity range for 0~<x~<0.45; (ii) T\*phase which is obtained as single phase only for x

We report on the interplay among the structural transitions, transport anomalies and superconductivity in (La\_,Ba,\_ySrY)~Cu04. For (La,\_,Bax)2Cu04 (y=O), it is now well established that high-T, superconductivity is suppressed in a narrow range of x around 0.0625. In this study, the amount of dop
