| Abstract | Ferroelectric thin films of Nd and Mn co-doped bismuth titanate, Bi$_{3.15}$Nd$_{0.85}$Ti$_{3−x }$Mn$_{x}$O$_{12}$ (BNTM) (x = 0–0.1), were fabricated on Pt/TiO$_{2}$/SiO$_{2}$/Si(100) substrates by a sol–gel technique. The BNTM films had a polycrystalline perovskite structure and uniform and dense surface morphologies. A lattice distortion was observed in the BNTM films due to Mn ion doping. The ferroelectric measurement of the films indicated that the values of coercive field (E $_{c}$) decreased gradually with the increase of the Mn content (x), however, the remanent polarization (P $_{r}$) increase firstly and then decrease with the increase of x. The sample with x = 0.05 had optimum electrical properties and a maximum 2P $_{r}$ value. The 2P $_{r}$ and 2E $_{c}$ values of the film at a maximum applied electric field of 400 kV/cm were 38.3 μC/cm$^{2}$ and 180 kV/cm, respectively. Moreover, this BNTM capacitors did not show fatigue behaviors after 1.0 × 10$^{10}$ switching cycles at a frequency of 1 MHz, suggesting a fatigue-free character. The main reason for the increase of the 2P $_{r}$ and the decrease of the 2E $_{c}$ might be attributed to the lattice distortion in BNTM films due to Mn ion doping. |

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.
