Abstract:
Superconducting compounds of composition Y sub(0.9) Pr sub(0.1Ba sub(2 [Cu sub(1-yZny] sub(3)O sub(7-delta) (0 less than or equal to y less than or equal to 0.10) have been synthesized. The structure of these materials has been studied using powder X-ray diffraction technique and refinement has been carried out by using Rietveld refinement procedure. It has been shown that all these compounds crystallize in orthorhombic structure with slight change in c parameter. Increase of parameter O(2) and decrease of parameter O(3)suggest the changes in the Cu-O2 plane of these orthorhombic materials on Zn substitution.
