| Summary: | In this study, the effect of ferrum doping in Bi l.6 Pbo.4Sr2Ca2Cu2.7Feo.30δ does
not show any superconducting behaviour. The sample was prepared by solid state
reaction method. The sample was characterised by using four-point probe and x-ray
powder diffraction (XRD). From the graph of normalised resistance versus
temperature, it shows that the sample exhibit a semiconducting behaviour. Thus,
the critical temperature, Tc of sample could not be determined. The critical current
density, Jc of the sample cannot be determined as well. The XRD pattern shows
the combination of 2212 and 2223 phases. It was observed that the structural
change by Fe doping is responsible for the decreased in critical temperature |
