| Abstract | A new exchange material, Mn/sub 78/Rh/sub 22/, is described, requiring no post-deposition anneal to obtain the antiferromagnetic phase and leading to spin valve sensors with good corrosion resistance, thermal stability up to 225/spl deg/C, and good exchange coupling characteristics. Potentiodynamic polarization scans performed in a sodium sulfate electrolyte show that Mn/sub 78/Rh/sub 22/ films exhibit a good corrosion resistance, comparable to that of Ni/sub 81/Fe/sub 19/, Mn/sub 80/Ir/sub 20/, and Mn/sub 50/Ni/sub 50/ films but with higher corrosion potential. Spin valve structures prepared with this exchange material show an exchange coupling strength (J/sub ex/) of 0.19 erg/cm/sup 2/. The blocking temperature (T/sub B/) of the as-deposited spin valve coupon samples is 235/spl deg/C. Unshielded sensors with trackwidths W=4-6 /spl mu/m and height h=1-2 /spl mu/m were fabricated. The sensors show well-linearized magnetoresistance (MR) transfer curves, without hysteresis or Barkhausen noise and are thermally stable under consecutive 5 h anneals in vacuum up to 225/spl deg/C. A shielded tape head device was fabricated showing a maximum output of 1.8 mV/sub pp///spl mu/m, with potential for operating at linear densities near 100 kfci, at which a 580 /spl mu/V/sub pp///spl mu/m output is measured. |

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.
