摘要：
The superconducting phase with mixed Tl and Bi, namely (Tl0.55Bi0.45)Sr2CaCu2Oy, was synthesized and characterized. Synthesis conditions were studied, and this phase, (Tl,Bi)-1212, was found to form preferentially to (Tl,Bi)-1223 when Sr was present with no Ba present. X-ray powder diffraction with Rietveld refinement provided structural data. The phase is tetragonal with a = 3.7988(4) A and c = 12.076(1) A, with space group symmetry P4/mmm, and with a platelet crystal morphology. Magnetic-susceptibility data gave an onset of superconductivity Tc at 94.9 ± 1.3 K with a Tcmid of 86.0 ± 1.1 K. Magnetic-hysteresis measurements showed that substantial flux pinning occurs in this phase at high temperatures.
