Structure and superconducting properties of fe doped of porous bscco 2223 superconductor / Norhaizam Mustaffa

Since the discovery of High-Temperature Superconductor (HTS) such as
BSCCO and YBCO, researchers have been carried out many attempts to
improve the superconducting properties. The effect of doping with different
ionic radii and different bonding characters element enhanced the electrical
properties. In this study, Fe doping in porous BSCCO 2223 was prepared to
study the effect of doping in a porous superconductor. The superconducting
properties, Tc and Jc were failed to improve due to the higher concentration of
Fe. The solid state method was used to prepare the sample. The sample
intensively undergone several characterization techniques to obtain the lattice
parameter and electrical properties. The critical temperature, Tc was determined
by measuring the resistivity using four-point probe technique. Analysis of
lattice parameter was observed by using X-ray diffraction (XRD) in relation to
electrical properties of superconductor.
