“…They all reveal a gradual reduction in value consequently upon doping for the untreated sample in agreement with the previous findings [17,24], except for the value of c for x 0X2, which is found to be slightly increased on doping. The suppression of T c in water treated YBa 2Àx Sr The corresponding values for the undoped sample are 10.9 K and 0.014, respectively, While the drop in T c on water treatment for the doped samples with x 0X4 and 0.6 is 3.4 and 7.3 K, respectively, being also much below the value of 10.9 K for the water treated undoped sample, the reduction in their oxygen content (0.017) is larger as compared to the undoped sample (0.014).…”

The partial substitution of Sr at Ba sites in YBa2—xSrxCu3O7—δ (0 < x < 0.6) has been carried out. The samples are treated with deionized water for 16 h. The influence of water on the corrosion resistance of YBa2—xSrxCu3O7—δ is examined by the changes in Tc, lattice parameters, orthorhombicity and oxygen contents. The results indicate that the corrosion resistance of YBa1.8Sr0.2Cu3O6.882 against treatment with water is enhanced.

“…The c lattice parameter of the xϭ0.0 sample is smaller than that of a pure Y:123 compound without Sr substitution, in agreement with the results reported on similar samples. 21,23,24 The decreased c lattice parameter substantiates the substitution of a smaller ionic size Sr atom at the Ba site in the system. With increasing Pr concentration x, the orthorhombicity of the system decreases.…”

“…%. 21,23,24 Therefore, it is of interest to study Sr substitution in R:123, say, Y:123 along with simultaneous Pr substitution at the R site. In this article we report our findings on the superconductivity, magnetism, and structural aspects of the Y 1Ϫx Pr x Ba 1.5 Sr 0.5 Cu 3 O 7Ϫ␦ system.…”

The results of superconducting and magnetic studies on the Y1−xPrxBa1.5Sr0.5Cu3O7−δ system with 0⩽x⩽1.0 are reported. Superconducting transition temperature (Tc) decreases with increasing x. The behavior of Tc(x)/Tc(0) versus Pr concentration x in this system is similar to that observed in the Y1−xPrxBa2Cu3O7−δ system but the critical Pr concentration (xcr) required for complete suppression of superconductivity appears to be higher in the present system. Surprisingly, the Néel temperature TN of PrBa1.5Sr0.5Cu3O7−δ is found to be higher (∼21 K) than that for PrBa2Cu3O7−δ (∼17 K) with nearly the same oxygen content. This may imply stronger interaction of Pr-4f moments with the carriers in the Cu–O2 planar network in the present system and yet the Tc suppression is relatively weaker.

The structure, normal state electrical transport and superconducting critical temperatures (T c ) of Y 1-x Pr x BaSrCu 3 O 7-δ (i.e., Y(Pr)-1113) and Y 1-x Pr x Ba 2 Cu 3 O 7-δ (i.e., Y(Pr)-123) systems, with 0.00 ≤ x ≤ 1.00 and 6.93 ≤ 7 -δ ≤ 6.95, have been investigated. Residual resistivity (ρ 0 ) and resistivity slope ((dρ/dT) cc ) corresponding to the linear ρ-T region are determined from the normal state resistivity measurements. It is found that an increase in ρ 0 and (dρ/dT) cc correlates with a decrease and enhancement of T c (x), respectively. Interestingly, in both the systems, the destruction of superconductivity seems to occur at the same value of x where (dρ/dT) cc tends to zero. The observed correlations suggest a possible mechanism of superconductivity in these systems, which is discussed.
