Preparation of Bi-Pb-Sr-Ca-Cu-O high-Tc superconductor from coprecipitated oxalates.

Primary Phase Field of the Pb-Doped 2223 High-Tc Superconductor in the (Bi, Pb)-Sr-Ca-Cu-O System

Both liquidus and subsolidus phase equilibrium data are of central importance for applications of high temperature supercon-ductors in the (Bi, Pb)-Sr-Ca-Cu-O system, including material synthesis, melt processing and single crystal growth. The sub-solidus equilibria of the 110 K high-Tc Pb-doped 2223 ([Bi, Pb], Sr, Ca, Cu) phase and the location of the primary phase field (crystallization field...

Preparation and Properties of High-T c Bi-Pb-Sr-Ca-Cu-O Thick Film Superconductors on YSZ Substrates

An evaluation of four firing profiles was performed to determine the optimum processing conditions for producing high-T c Bil.8Pb0.33Srl.87Ca2Cu30 x thick films on yttriastabilized zirconia substrates. Using these four profiles, the effects of sintering temperatures of 830-850°C and soak times of 0.5 to 12 hours were examined. In this study, Tc,zero values of 100K were obtained using a firing p...

High resolution electron microscopy study of the high Tc superconductor Tl 0 . 5 Pb 0 . 5 Sr 4 Cu 2 CO 3 O 7

2014 The structure and the microstructure of the new high Tc superconductor Tl0.5Pb0.5Sr4 Cu2CO3O7 have been studied by high resolution electron microscopy. The experimental images fit well with the calculated ones based on a structure built up from the intergrowth of a 1201-type slice [Tl0.5Pb0.5Sr2CuCO5]1201~ with a [Sr2CuCO3O2]~ unit. The comparison of the calculated and experimental images ...

Electronic structure of the trilayer cuprate superconductor Bi(2)Sr(2)Ca(2)Cu(3)O(10+delta).

The low-energy electronic structure of the nearly optimally doped trilayer cuprate superconductor Bi(2)Sr(2)Ca(2)Cu(3)O(10+delta) is investigated by angle-resolved photoemission spectroscopy. The normal state quasiparticle dispersion and Fermi surface and the superconducting d-wave gap and coherence peak are observed and compared with those of single- and bilayer systems. We find that both the ...
