TLDR
In this article, the electrical resistivity and magnetic properties of GdBaSr 1− x Nd x Cu 3 O y (where x ǫ = 0, 0.1, 0.2 and 0.3) were studied by powder X-ray diffraction and SEM analysis and the optimal sintering temperature of the compounds was found to be 950°C.Abstract:
The compounds GdBaSr 1− x Nd x Cu 3 O y (where x = 0, 0.1, 0.2 and 0.3) were prepared using the solid-state reaction technique. The single phase and microrange crystalline nature of the compounds were studied by powder X-ray diffraction and SEM analysis. The electrical resistivity and magnetic properties of the compounds were studied as a function of temperature. A decrease in superconducting transition temperature for an increase in Nd substitution was observed. A decreasing trend of diamagnetic strength and an increasing trend of magnetic moment of the samples with Nd substitution were observed from magnetization measurement. The optimal sintering temperature of the compounds was found to be 950 °C.read more

Effect of Zn doping on the superconductivity of RBa2Cu3−xZnxO7−y (R = Yb, Er, Y, Dy, Gd, Eu, SmandNd)
TL;DR: In this article, the superconducting-nonsuperconducting transition accompanied by a transition into the semiconducting phase in these systems is interpreted in terms of a Mott transition, and the reduction of T c by Zn doping in RBa 2 Cu 3− x Zn x O 7− y was found to be strongly dependent on the ionic radius of the rare earth element R.
