| Abstract | A CeO/sub 2/ buffer layer was deposited by the pulsed laser deposition (PLD) method on a YSZ single crystal substrate and an IBAD-Gd/sub 2/Zr/sub 2/O/sub 7/ substrate. It was investigated in terms of the effect of the CeO/sub 2/ layer thickness for YBa/sub 2/Cu/sub 3/O/sub 7-X/ (YBCO) coated conductors by the metalorganic deposition method using trifluoroacetates (TFA-MOD). The grain alignment, delta phi, and surface roughness, R/sub a/, of CeO/sub 2/ layers were improved with increasing the thickness for both kinds of substrates of a YSZ single crystal and an IBAD-Gd/sub 2/Zr/sub 2/O/sub 7/ substrate. Especially the improvement of the qualities of the CeO/sub 2/ layer on the IBAD substrate was remarkable. The initial value of delta phi was 12 degree at the surface of the IBAD-Gd/sub 2/Zr/sub 2/O/sub 7/ layer without a CeO/sub 2/ layer while it decreased to 4 degree after 600 nm thick CeO/sub 2/ layer deposition by PLD. Consequently, the J/sub c/ value of the YBCO on the CeO2 buffered IBAD-Gd/sub 2/Zr/sub 2/O/sub 7/ metallic substrate exhibited the value as high as 2.9 MA/cm/sup 2/ at 77 K and 0 T. This result implies that a high rate deposition by PLD could be used for further texture evolution even after thin film IBAD deposition which could result in shortening of the overall production time for the buffer layers deposition. |

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.
