  A New Approach of Synthesis Fe-Substituted Bi-2223 Superconductors

  By Rohitash Kumar

  Abstract: Generally, the Bismuth based high temperature superconductors are utilizing in three phases as Bi-2201, Bi-2212 and Bi-2223. These have different transition temperature according to superconducting phase. Here, we studied about Bi-2223 phase by using complex Bi2Sr2Can-1 (Cu1-xFex)3O10+δ where n = 3. In this complex, we has been doped iron in Coper (Cu) site (x = 0.07%). This sample was prepared by solid state reaction method. The planetary Ball mill was …

  The Formation of Bi-2223 Superconductor with Fe-Substitution

  By Rohitash Kumar, H. S. Singh, Y. N. Singh

  Abstract: Presently, we have studied about synthesis and characterization of Bi-2223 Superconductors in the form of Bi2Sr2Ca3(Cu0.97Fe0.03)3O10+δ complex. The sample was established with solid state method and characterized by XRD, (FESEM) and (FTIR). The DC electrical resistivity of the sample was measured at liquid helium temperature. The XRD parameters shows the orthorhombic structure with lattice constant a = 5.7429Å, b = 5.0845 Å, c = 36.5569 Å and grain size confirm …
