Abstract

We prepared various RuSr₂Nd_xGd_1-xCu₂O₈ samples with systematically varying Nd amounts by x = 0, 0.09, 0.18 and 0.35. The solid state route involved mixed oxides (Nd_xGd_1-x)₂O₃ obtained by coprecipitation. The XRD and microstructural analysis showed that a high phase purity was obtained. The Nd solubility limit can be placed between x = 0.18 and x = 0.35. The superconducting transition temperature dramatically decreased with increasing Nd content, confirming that Nd entered the lattice. The field dependence of superconducting transitions exhibited a polycrystalline behaviour.
