Abstract:We have studied for the first time the effect of Ag addition (0-15 wt%) to the superconducting system, Nd 1.85 Ce 0.15 CuO 4 , on its crystal structure and local structural features, using synchrotron X-ray diffraction (SXRD) and Raman spectroscopy, respectively. SXRD and subsequent Rietveld refinement studies on powders of Nd 1.85 Ce 0.15 CuO 4 + Ag system indicate a small but significant change in lattice parameter upon Ag addition, showing evidence for possible incorporation of Ag to the extent of ∼1 wt%.
