Synthesis and Characterization of Fe doped Bi2Sr2Ca1Cu2O8

Abstract

Bi2Sr2CaCu2O8 (BSCCO) was prepared by solid state route method. Our aim is to dope BSCCO with a magnetic material such as Fe to enhance its current density. Samples were prepared by conventional solid state reaction method followed by sintering at 880oC. Critical temperatures of the samples were determined by resistivity temperature measurements using four probe technique at liquid nitrogen temperatures. Tc values for the samples were in the range (Tconset ~ 78 – 60K). XRD analyses were done and lattice parameters of the samples were determined by indexing the diffraction peaks. Surface of the samples was studied by scanning electron microscope (SEM) micrographs at a magnification of X1000.
