| Abstract | Summary form only given. Surveys the status of spin transport materials and device research, and gives the author's opinion regarding the risks and opportunities which these new materials represent for semiconductor device research. The physical understanding of these new devices is based on the existence of two types of carriers in ferromagnetic conductors, one type with a magnetic moment in the same direction as the magnetization of the material, and the other type with a spin in the opposite direction. A two current model similar to that used for n and p carriers in semiconductors is used to explain operation of the giant magnetoresistance (GMR) and spin dependent tunnelling (SDT) structures. A summary of research results is given for GMR, SDT, and hybrid magnetic/semiconductor devices, along with a summary of proposed applications of these structures. These spin transport structures could provide competition for existing semiconductor technology in the areas of 1) nonvolatile random access memory, 2) magnetic field sensors (e.g. Hall effect sensors), and 3) (in the long term) general active devices. Each of these areas is discussed with an estimate given for the likelihood of success for these new devices. |

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.
