The interface of epitaxial c-axis-oriented (Bi, Pb)2Sr2Can-1 CunO2n+4+x thin films grown by rf sputtering on MgO substrates has been investigated by high-resolution transmission electron microscopy. It was found that, in spite of the roughness of the

Tl-Ba-Ca-Cu-O thin films have been grown on a variety of substrates, both with and without the use of buffer layers. Differences in processing routes required for the various film-substrate combinations are highlighted and the effect of the buffering

Bi(Pb)-2223/Ag powder in tube tapes have been examined by TEM. 5The tapes show good alignment and phase purity in the SEM but TEM investigations revealed a number of fine-scale, current-limiting, features. Such features include variation in grain bou

The effect of processing conditions on microstructure and phase development has been investigated for TlBi-1223 tapes made by a melt processing route. Increasing loss of crystallinity and phase decomposition into Tl-1212 and SrCaCu-oxides is seen for

With a view to the long term exploitation of the high upper critical fields of high temperature and Chevrel phase superconductors and their use in very high field superconducting magnets, we are making measurements of critical currents on practical v

We present results of innovative measurements of critical direct current transport currents at 4.2 K of the high-temperature superconductor, BiSrCaCuO(2212), in pulsed magnetic fields up to 31.5 T at an electric field criterion of 100 mu V m-1. Up to

Tl2Ba2Ca1Cu2Ox thin films with excellent alignment have been grown on CeO2 buffered R-plane sapphire using an ex situ anneal step in argon atmospheres at temperatures of 720-740°C. With this low-temperature process we have overcome the serious probl
