| Abstract | We studied Pt-Cr binary alloys as a possible material for the intermediate layer (IML) in CoCrPt-SiO2 perpendicular recording media. We investigated the magnetic properties, structural properties, and recording performance of CoCrPt-SiO2 media with Pt-Cr alloy IMLs as a function of the Cr composition in the Pt-Cr IMLs. The CoCrPt-SiO2 media exhibited the best recording performance at the Cr composition from 20 to 30 at.%, where the structural and magnetic defects in the CoCrPt-SiO2 layers appeared to be minimized. Plan-view transmission electron microscopy images revealed that the addition of Cr into a Pt IML reduces the size of the crystal grains in the IML and promotes the formation of the oxide grain boundary in the CoCrPt-SiO2 layers. |

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.
