Thin films of pure single phase and phase have been prepared by laser ablation and post-annealing. In particular, when both films were annealed at a low temperature and for a long time, they had a highly c-axis-oriented structure and a high transport

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

Measurements of the time decay of the remanent magnetization of a polycrystalline sample of (Tl/Pb) (Ba/Sr)2Ca2Cu3O9 (Tl- (1223)) with a zerofield Tc of 119 K have been carried out for T=90, 100 and 105 K by cooling in a DC field H between 50 and 10

We report on a method for predicting the DC voltage versus current characteristics of thin polycrystalline high-temperature superconductor samples from critical density ( J c ) distributions determined from AC susceptibility measurements. A sample ma

Thin films of the (1223) phase of the TlSrCaCuO system (Tl-(1223), single TlO layer) and the (2223) phase of the TlBaCaCuO system (Tl-(2223), double TlO layers) were prepared by the laser ablation method. The irreversibi

A linear motor car using the diamagnetism of a high Tc superconductor has been manufactured. In this model the track is constructed by Sm-Co permanent plate magnets magnetized perpendicularly to the plane. The car is comprised of Tl based superconduc

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

Metal-sheathed tapes with Tl-(Ba/Sr)-Ca-Cu-O (TBSCCO) system were fabricated using the drawing-rolling method combined with a pressing process in order to improve the weak link properties. The Tc's of the tapes were measured to be 115±2K. The Jc was

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
