| description | The coprecipitation technique was used in the preparation of samarium doped
Bi₁.₆Pb₀.₄Sr₂Ca₂Cu₃O₁₀ polycrystalline ceramic superconductor. In this study, four sites
(calcium, bismuth, strontium and copper) were separately subjected to Sm doping with
nominal composition ranging from x=0 to x=0.3 at different sintering times. The
superconducting properties of the samples have been investigated. The pure sample,
which exhibits TC(R=O) around 102 -103 K and TC-onset around 108 K, showed large flaky
grains of ~7 µm in size which are randomly distributed_ However at longer sintering
time the pure superconductor showed a better orientation as compared to that of the
short sintering time sample. The calculated value of Josephson current 10 , obtained from
the ac susceptibility data showed a much higher value (I₀=138.7µA) as compared to the
conventional prepared to that of the sample prepared by conventional method (I₀=55.9 µA). This indicates better grain connectivity and higher 2223 phase content,
which was confirmed by SEM photographs |
