Abstract

The effect of In2O3addition on (Bi1 6Pb0.4)Sr2Ca2Cu3O10(In2O3)x(x = 0 - 0.1 weight percent) was investigated. The characterization includes X-ray diffraction method, microstructural, electrical resistance, AC susceptibility and intergrain critical current density. The onset transition temperature, Tc onsetand zero resistance temperature, Tc zerowas 112 K and 90 K, respectively for the x = 0 sample. XRD patterns showed that the volume fraction of the (Bi1 6Pb0.4)Sr2Ca2Cu3O10(Bi-2223) and (Bi1 6Pb0.4)Sr2CaCu2O8(Bi-2212) phase was almost equal. AC susceptibility measurements were performed at a frequency of 295 Hz and magnetic field (H) 5 Oe. Two distinct step-like transitions were observed in the AC susceptibility measurements for x = 0 indicating the existence of Bi-2223 and Bi-2212 phases. The highest peak loss temperature, Tpfrom the imaginary part χ” of the susceptibility were 74 K and 104 K for the x = 0 sample. Tpshifted to lower temperatures with increasing In2O3content, indicating that magnetic flux penetrated between the grains at lower temperatures as In2O3content was increased. The curve of Tpalso broadened with increasing In2O3.This indicated the weakening of intergranular coupling and lowering of the flux pinning energy. The intergrain critical current density at the peak temperature Jc(Tp) was measured using the Bean's model and the values were between 16 and 20 A cm-2for all samples. A schematic model for induced current in a polycrystalline material with two superconducting phases of equal volume fraction but different transition temperature is discussed.
