| Abstract | The preparation and soft magnetic properties of (Co$_{0.6}$Fe$_{0.3}$Ni$_{0.1}$)$_{70−x }$(B$_{0.811}$Si$_{0.189}$)$_{25+x }$Nb$_{5}$ (x = 0–4) glassy alloys were investigated. This multicomponent system was found to exhibit a distinct glass transition and a wide supercooled liquid region of over 50 K before crystallization. As a result, the (Co$_{0.6}$Fe$_{0.3}$Ni$_{0.1}$)$_{70−x }$(B$_{0.811}$Si$_{0.189}$)$_{25+x }$Nb$_{5}$ bulk glassy alloys with diameters up to 5 mm were produced by copper mold casting. In addition to high glass-forming ability, the Co-based glassy alloys also exhibit excellent soft-magnetic properties, i.e., saturation magnetization of 0.54–0.72 T, low coercive field of 0.7–1.4 A/m, and high effective permeability of 18,600–22,400 at 1 kHz under a field of 1 A/m. Furthermore, the giant magneto impedance effects of the (Co$_{0.6}$Fe$_{0.3}$Ni$_{0.1}$)$_{68}$(B$_{0.811}$Si$_{0.189}$)$_{27}$Nb$_{5}$ glassy ribbon at different driving frequencies were also investigated. The results show that the largest impedance ratio is as high as 138 % at the frequency of 2.5 MHz under an ac current of 0.2 mA, together with high field sensitivity of 12.5 %/Oe. |

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.
