| Abstract | Summary form only given. In order to achieve high density and low noise recording performance in perpendicular magnetic recording media, extremely thin films, which consist of fine grains with high magnetic anisotropy energy are essentially required. Hexagonal ferrite thin films, such as Ba-ferrite (BaM), are regarded as one of the candidates for the perpendicular magnetic recording media. It is reported that BaM thin films with several nano-meter thicknesses could be deposited on the Pt[111] underlayer by facing targets sputtering (FTS) system, because of the suppression of radiation damage to the growing films by the high energy negative oxygen ions. However, perpendicular coercivity H/sub c/spl perp// of such a thin BaM films deteriorated for the thickness below 40 nm. Sr ferrite (SrM) is hopeful for its higher magneto-crystalline anisotropy constant than that of BaM. In this study, extremely thin Sr ferrite (SrM) layers with several nano-meter thickness were deposited on Pt[111] underlayer using facing targets sputtering apparatus without post-annealing. A mixture gas of Kr and Ar was effective to prepare extremely thin SrM films. |

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.
