Abstract
The influence of Sb2O3 dopant on the superconductivity and the phase formation of the Bi(Pb)-Sr-Ca-Cu-O system was studied using differential thermal analysis/thermogravimetric analysis (DTA/TGA), X-ray diffraction (XRD), transmission electron microscopy (TEM), a.c. susceptibility and resistance measurements. It was found that the solubility of Sb3+ in the 110 K superconducting phase is limited; instead Sb3+ readily combines with other elements to form one or more unknown second phase(s), which melt at lower temperatures and accelerates the formation of the 110 K phase. Resistance measurements show the transition initiation temperature of the 110 K superconducting phase is unchanged but thatT c (zero) was found to decrease from 107 K to 98 K. TEM examination generating lattice images from antimony-doped crystals, showed the structure to be inhomogeneous and to contain many defects.
