| Abstract | We fabricated (Co-alloy)-SiO/sub 2/ granular films by rf-sputtering with composite target and annealing in a high vacuum environment. The coercivity of the films depended on annealing temperature, the Co-alloy's volume fraction in the film, and other added elements to cobalt. We found that a (Co/sub 85/Pt/sub 15/)/sub 83/-(SiO/sub 2/)/sub 17/ granular film (Co/sub 85/Pt/sub 15/: 64 vol.%) exhibited about 1600 Oe of coercivity at room temperature. The grains diameter was about 50 nm measured by AFM. X-ray diffraction patterns showed that the Co-alloy grains of most films had an fcc-phase structure. From Henkel-plot analysis, the magnetic exchange interaction between the CoPt grains was found to be weak. |

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.
