Abstract | The giant magnetoimpedance (GMI) effect of CuBe/NiFeB and CuBe/insulator/NiFeB composite wires prepared by electroless-deposition was investigated. The results showed that geometry dimension has a significant influence on the GMI effect of CuBe/NiFeB composite wire. As the NiFeB layer thickness approaches the skin depth of the NiFeB layer, maximum GMI will be expected; it reaches -23% at 1 MHz. After adding an insulator layer, the GMI ratios of CuBe/insulator/NiFeB composite wire were much higher than those of CuBe/NiFeB composite wire. The maximum GMI ratio of CuBe/insulator/NiFeB composite wire was 250% at 500 kHz-1 MHz. This result is related to current redistribution under the external magnetic field and the electromagnetic interaction between the conductive core and the ferromagnetic layer, and also is related to the skin effect and eddy current of the sample. |

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.
