| Abstract | A series of samples with nominal compositions of YBa2-xNdxCu3Oy were prepared by solid state reactions and investigated by X-ray diffraction, magnetic and electrical measurements. The solubility, x, was determined to be x<0.25. It is found that the solubility of rare earth Re ions at the Ba-sites in Re1+xBa2-xCu3Oy is strongly related to a geometric parameter, the tolerance factor t. For x<0.25, Tc0 are all above 92 K. For x>0.3 Tc0 drops sharply to about 84 K, and finally for x=0.5 Tc on falls to 30 K and Tc0 is below 10 K. Our results suggest that the small compatibility of Nd and Ba in YBa2 Cu3Oy system does not seriously suppress the superconductivity. |
