| Abstract | YBa/sub 2/Cu/sub 3/O/sub 7-x/ (YBCO) thick films have been grown on buffered metal substrates at different deposition rates by pulsed laser deposition (PLD). In-plane texture and superconducting properties of YBCO films have been systematically investigated. It was observed that the in-situ epitaxial growth of YBCO films on buffered metal substrates could be achieved at a very high deposition rate. Under the optimized deposition conditions, X-ray diffraction measurements showed that both in-plane and out-plane texture of YBCO films were mainly dependent on the texture quality of the buffer-layer not the deposition rate. As the deposition rate increased from 1 nm/s to 30 nm/s, the average phi-scan rocking curve of YBCO films was only increased from 10 degree to 12 degree. The omega scan rocking curves kept the same FWHM value of 2 degree. Critical current densities J/sub c/ of the order of 10/sup 6/ A/cm/sup 2/ at 77 K and self-field have been achieved at high deposition rate of 30 nm/s by optimizing deposition parameters. Our results demonstrate the practical possibility of YBCO thick film processing at very high deposition rate by PLD on buffered metal substrates. |

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.
