| Abstract | The effect of z value on the high temperature performance of Sm(Co/sub 0.795/Fe/sub 0.09/Cu/sub 0.09/Zr/sub 0.025/)/sub z/ with effective z=7.14-8.10 was studied up to 600/spl deg/C. It was observed that the intrinsic coercivity (/sub M/H/sub c/) was very sensitive to the z value, especially when the temperature was lower than 550/spl deg/C. Peak values of /sub M/H/sub c/ were observed in the /sub M/H/sub c/-z curves. As the temperature rose, this peak shifted toward lower values of z. It was observed in this study that a new magnet with the composition of Sm(Co/sub 0.795/Fe/sub 0.09/Cu/sub 0.09/Zr/sub 0.025/)/sub 7.26/ showed maximum energy product more than 20 times higher than the best conventional high temperature 2:17 magnet in a dynamic characterization at 4000/spl deg/C. The new magnets with low z values and low Fe (high Co)content also displayed excellent long-term stability at 500/spl deg/C. |

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.
