| Abstract | From optical wave-guide experiment in rare-earth and bismuth-substituted iron garnet films, it is shown that the optical birefringence Δn presents important contributions Δnσ and Δ nG arising from stress-induced (photoelastic) and growth-induced birefringences which depend on the chemical composition, growth temperature TG and orientation of the film. The dependence of Δn σ on TG is directly associated with the variation of the segregation coefficients of the different ions substituted in the garnet which changes their content and therefore the lattice mismatch between the films and the substrates. On the other hand ΔnG seems to be independent on TG. In (110)-oriented Bi-YIG films anisotropic behaviours have been observed for Δnσ. The different contributions to Δn are determined and discussed from theoretical models. |

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.
