| Abstract | Solid solutions of BiFeO$_{3}$ (BFO) and NaNbO$_{3}$ [i.e., (Bi$_{1−x}$Na$_{x}$) (Fe$_{1−x}$Nb$_{x}$)O$_{3}$] for x = 0.1, 0.2, 0.3 were prepared by a mixed-oxide method. X-ray diffraction analysis confirms the formation of a single-phase system within a certain limit of x, and indicates that with increase in concentration of NaNbO$_{3}$ there is structural transformation of BFO from the rhombohedral to the tetragonal phase. The dielectric constant and loss-tangent of samples increase with rise in temperature. It is found that with increase of concentration of NaNbO$_{3}$ in the solid solution, tangent loss of BFO is greatly reduced that can be useful for some industrial applications. The appearance of hysteresis loops of the samples at room temperature confirms the ferroelectric properties of the materials. As the electrical conductivity of the above system increases with rise in temperature, it follows the Arrhenius relation. The frequency and temperature dependence of conductivity of the above system obeys Joncher’s universal power law. Some voltage is induced with the application of magnetic field confirming the existence of multiferroics properties in the materials. Leakage current reduces with increase in content of NaNbO$_{3}$ in the solid-solutions. |

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.
