| Abstract | NiZn ferrite thin films with spinel structure have been deposited successfully on glass substrates at a relatively low temperature by means of the Facing Target Sputtering (FTS) technique. In addition to substrate temperature, PO/sub 2//P (O/sub 2/ partial pressure over total sputtering pressure) ratio was found to be another major factor in controlling the in-plane coercivity H/sub c/ and saturation moment density M/sub s/ of NiZn ferrite thin films. The increase of M/sub s/ is attributed to the increase of the substrate temperature or the decrease of PO/sub 2//P ratio; the decrease of H/sub c/ is associated with the increase of both substrate temperature and PO/sub 2//P ratio. It is believed that the PO/sub 2//P ratio plays a critical role in the formation of NiZn ferrite film, which determines the magnetic properties of the film. With the increase of PO/sub 2//P ratio, the NiZn thin film changes from a strong (111), (311) texture-dominated polycrystal structure to an amorphous structure and the grain size become smaller. In this study, sputtering conditions of NiZn ferrite films were optimized to achieve a low in-plane coercivity H/sub c/ and a relatively high saturation moment density M/sub s/. |

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.
