Özet:

 

In this work we studied the effect of La-doping on phase  purity, crystal structure and electrical resistivity of  Bi2Sr2Ca2Cu3O10+d superconductor, synthesized by usual  solid state reaction method.  The X-ray florescence (XRF) show the  stoichiometry of samples and X-ray diffraction (XRD) analysis showed  the change of structure from orthorhombic to tetragonal by increasing  La doping.  It was found that the change of lanthanum concentrations  of all our samples produce a change in the oxygen content, the ratio  of lattice parameters c/a and mass density rm.  Electrical  resistivity, using the four-probe technique, was used to find the  critical temperature Tc and to put in evidence metallic and  semiconducting behavior in normal state.
