The degradation in 77 K self-field critical current density ( J c ) of electrophoretically deposited Bi-2212/Ag tapes has been evaluated separately for thermal cycling (320–77 K), bending in compression, tension and combined compression-tension. Af

In order to improve pinning properties of bulk Bi 2 Sr 2 CaCu 2 O 8+ δ (Bi-2212) materials, samples of both pure Bi-2212 and Bi-2212 with carbon nanotubes embedded (CNTE Bi-2212) have been prepared by partial-melting processing. The preparation cond

Flux distributions of partial-melting processed Bi 2 Sr 2 CaCu 2 O 8+ δ ceramics are obtained using magneto-optic imaging. In remanent states ( μ 0 H a =0 T), large amounts of trapped flux are observed along (Sr,Ca) 2 CuO y particles embedded in th

The partial melting behavior in the electrophoretically deposited Bi 2 Sr 2 CaCu 2 O 8+ δ /Ag tapes has been investigated. The results indicate for the first time that the partial melting is non-uniform in the beginning, that is, the partial melting

MgO or particulates were introduced into Bi-2212/Ag tapes during the fabrication process with the intention of producing flux pinning centres. It was found that (i) MgO or normal particles added to Bi-2212 superconductor do not react chemically with

Highly c-axis-oriented Bi2Sr2CaCu2Oy/Ag tapes with high critical current density (Jc) were prepared by electrophoretic deposition followed by partial-melt processing. Slow cooling at 0.2 degrees C min-1 from the partial-melt temperature and a subsequ

Efforts are being made to improve the pinning and grain coupling in Bi23r2CaCu2O8+δ ceramics. For this purpose, the penetration of vortices is visualized by means of magneto-optical garnet indicators at temperatures up to 77 K. It is shown that ther

In this work, we have prepared both Bi2Sr2CaCu2O8+δ samples (Bi-2212) and Bi2Sr2CaCu2O8+δ samples with carbon nanotubes embedded (CNTE Bi-2212) by partial-melting processing. AC susceptibility measurements show that the Bi-2212 samples as well as t
