Abstract | Doping effects of acidic (pH4) and basic (pH10) Fe3O4 on the magnetic properties of ZrO2 have been reported in this paper. Fe3O4 doped zirconia (FZ) sol is synthesized by varying Fe3O4 concentrations in the range of 2-10 wt% using sol-gel route. FZ sols are spin coated onto glass substrates and then vacuum annealed at 300 °C for 60 min in the presence of 500 Oe magnetic field. X-ray diffraction results show amorphous behavior at 2 wt% doping in both acidic and basic cases. Mixed monoclinic-tetragonal behavior is observed in acidic films with 6-10 wt% doping concentration. However, tetragonal phase is observed in basic films with 8-10 wt% doping. Soft ferromagnetic behavior is observed in both the acidic and basic doped zirconia. Saturation magnetization (Ms) of ~33 emu/g is observed in acidic FZ samples whereas, variation in Ms (1-36 emu/g) is observed in basic FZ samples. Iron oxide stabilized ZrO2, with soft ferromagnetic behavior, can be employed for coatings on teeth as well as for diagnosis and therapy of oral cancer. |

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.
