| Abstract | Superconducting Bi-(2223) multifilamentary tapes with Ag/sub 100-x/Y/sub x/ alloy sheaths, with Y=Cu, Mn and Pd, were made by the oxide-powder-in-tube technique. All resistivities of the Ag alloy sheaths exceed that of the pure Ag sheath by at least a factor of 2. The maximum resistivity was achieved for Ag/sub 99/Pd/sub 1/ with /spl rho//sub 77K/=1.3 /spl mu//spl Omega/cm. Tapes sheathed by Ag/sub 90/Cu/sub 10/ exceed the critical current density, J/sub C/, of pure Ag sheathed ones. J/sub C/ up to 26 kA/cm/sup 2/ were achieved by pressing Ag/sub 90/Cu/sub 10/ sheathed tapes during the thermo-mechanical-treatment, TMT. For thinner Ag/sub 90/Cu/sub 10/ sheathed tapes up to 31 kA/cm/sup 2/ were obtained employing flat rolling during TMT. Measured irreversibility lines of thin and thicker tapes with comparable J/sub C/ suggest, that thicker tapes have a larger pinning strength and a better grain texture but thinner ones a better grain-to-grain connectivity. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
