| Summary: | <b>Abstract :</b><p align=\"justify\">out on the synthesis of high Tc superconductor Bi<sub>1,8</sub>Pb<sub>0,4</sub>Sr<sub>2</sub>Ca<sub>2</sub>Cu<syb>3</sub>0<sub>10+x</sub>by means of solid state reaction proceeded by wet mixing . The analysis of data from several characterization that sample was carried out to explain new phenomena in high Tc superconductors. The resistance measurement was obtained T<sub>c on</sub> = 112K and T<sub>c0 </sub>= 102,8K. The analysis of data of resistivity explained excess conductivity phenomena and mean field transition temperature T<sub>GL</sub> = 108,9K has been obtained in terms Aslamazov-Larkin theory for temperature above the mean field transition temperature. And within context of Kosterlitz-Thoules theory at temperature below the mean field transition temperature was found broadening characteristic T<sub>C</sub> = 0,058 and T<sub>KT </sub>= 102,5K. The analysis crossover dimensional was found Josephson Coupling energy J = 37,17K - 44,60K and effective interlayer distance, d about 26,38A. Then, in this study was investigated anisotropy <br />
parameter of resistivity ? ? 20,4 although rough estimation only. In the last step this paper was performed existence Thermally Activated Flux Flow (TAFF) phenomena which was obtained by I-V characteristic measurement. |
