| Abstract | For studying the influence of the current passed through a metal line for the magnetic cells on semiconductors, we prepared two types of the devices. Case 1 is that only one patterned permalloy cell on top of the insulated metal strip, and two cells are beside the strip. Case 2 is that all three patterned magnetic cells are on top of the strip. The magnetic field needed to reverse the magnetization of a submicrometer-size permalloy single domain cell with aspect ratio of 6 is larger than that of a unpatterned millimeter-size permalloy thin film due to the dimension effect. Magnetic force microscopy images of the patterned cells before and after applying various electrical currents were investigated. We have observed that: 1) the magnetic field produced by the word line will not change the magnetic configuration of the magnetic cells near the wires; 2) the magnetic field produced by the word line is quite uniform; and 3) for small aspect ratio of the submicrometer magnetic cells (<6), the magnetic configuration becomes multidomain, and higher magnetic field needed to reverse its magnetic state. Finally, we have shown a method that integrates an electric wire on semiconductors for generation of surrounding magnetic fields and patterned magnetic cells on micrometer length scales. |

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.
