| Abstract | Fluctuation conductivity analysis was carried out to characterize NdBa/sub 2/Cu/sub 3/O/sub y/ superconductors with the different amounts of Nd/sub 4/Ba/sub 2/Cu/sub 2/O/sub y/ (Nd422) phase. Samples were prepared by melt-textured process from the mixtures in molar ratios of Nd123: Nd422 = 1:x (x = 0.2, 0.25, 0.3). The conduction dimensionality and the fluctuation amplitude were obtained by analyzing the fluctuation conductivity. The dimension of conduction on excess conductivity showed little variation by the addition of 422 phase. The coherence length and the correlation length obtained by this analysis became larger with increasing amount of 422 phase. The clear evidence was found that the pinning force in the sample was well correlated with the characteristic length of superconductivity. |

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.
