IMPACT OF Zn SUBSTITUTION ON PHASE FORMATION AND SUPERCONDUCTIVITY OF Bi_1.6Pb_0.4Sr₂Ca₂Cu_3-xZn_xO_10-δ WITH x = 0.0, 0.015, 0.03, 0.06, 0.09 AND 0.12

Abstract

Cu/Zn substitution of around more than 1at% [19,20].In the present letter in order to revisit the Zn substitution in Bi-2223 system, we carefully synthesized these compounds and characterized them for phase formation, RESULTS AND DISCUSSIONThe Structural phase characterization was carried out by powder X-ray diffraction employing Cu K radiation and the XRD data corresponding to all the samples are plotted 4 in figure 1. It is seen in the diffraction pattern that Zn doping only has little effect on reflection-intensity profile as a function of the angle of diffraction. The XRD data has been indexed using an orthorhombic unit cell and the most intense reflections appearing in the XRD spectra of each sample are listed in table 1. The appearance of strong reflections corresponding to the (002), (0012) and (0014) CONCLUSIONIn conclusion, we had synthesized nearly phase pure samples of series
