The intergrain critical-current-density (${\mathit{J}}_{\mathit{c}\mathit{i}}$) distribution and intergranular volume fraction of ceramic superconductors were determined from ac-susceptibility measurements. The sample was melt-treated polycrystalline

The surface structural chemistry of the high- T c superconductor, (Tl, Pb)Sr 2 Ca 2 Cu 3 O 9 (Tl-1223), has been investigated by high resolution electron microscopy. Clean and flat (114) and (001) surfaces were observed using a profile imaging techni

A strongly pinned (TI/Pb)-(Sr/Ba)-CaCuO bulk superconductor of TI-(1223) phase with a single TI-O plane has been developed with a magnetic J c over 43 000 A cm −2 at 77 K and about 600 000 A cm −2 at 20 K and 1 T. Single crystals of TI-(122

The presence of pinning centers in high temperature superconductors (HTSCs) is a prerequisite for obtaining a high critical current density ( J c ) in a magnetic field. We have discovered that, perhaps more generally, HTSCs having only a single layer

Pinning centers were successfully introduced into the (1223) phase of Tl–Sr–Ca–Cu–O system using its derivative (Tl/Pb)–(Sr/Ba)–Ca–Cu–O with the nominal composition of (0.5/0.5)−(1.6/0.4)–2–3. The bulk sample showed a strong flu

The Tl-Sr-Ca-Cu-O system gives rise to two superconducting phases with a single Tl-O plane, i.e. the (1212) and (1223) phase. Introduction of pinning centers into the Tl-(1223) phase has been performed by modifying the atomic compositions and by opti

The existence of effective pinning in single T1-layer 1223 superconductors has been reported [1–3], as opposed to lower values in T1- and Bi-double layer systems, which is intimately related to their crystal structures. In order to investigate the

We report on the superconductivity and crystal structures in Tl-(Ba,Sr)-Ca-Cu-O (TBSCC) system. In the case of TBSCC system, the 2223 phase was obtained as a single phase more easily compared with the Tl-Sr-Ca-Cu-O and Tl-Ba-Ca-Cu-O systems. As a res
