| Abstract | Superconducting thin-films of YBa 2CU 3O 7-X material have been grown in situ by single target d.c. sputtering, Single-crystal (100)MgO, (100)SrTiO 3 and (110)SrTiO 3 substrates were heated between 600 and 700 C and the film orientation has been studied as a function of substrate temperature. X-ray diffraction photographs, taken in a Weissenberg camera, were used to study the in-plane orientation of the films and to determine the epitaxial growth relations with the substrates. Films displayed only textured growth near 650 C and epitaxial growth near 700 C. These thin-films have been measured by resistive and inductive techniques. Best samples, obtained on SrTiO 3, exibit onsets between 87 and 89 K, ( R = 0) between 85 and 87 K and critical current densities of about 10 6 A cm -2 at 77 K. The transition width of these samples, as determined from the inductive response, is less than 1 K. We observed a clear correlation between the width of the a.c. inductive transition and the film quality and used this sensitive method for deposition-parameter optimization. |

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.
