Abstract

Present communication describes the preparation and the influence of Pr₂O₃ and Nd₂O₃ on structure, ferroelectric, dielectric, pyroelectric and resistivity properties of (Ba _1-x Sr_x)₂NaNb₅O₁₅[BSNN] compositions at and around × = 0.6, MPB region. Substitution of Pr ₂O₃/Nd₂O₃ decrease the cell volume and Curie temperature and enhance the room temperature dielectric constant. The room temperature pyroelectric coefficients are observed to be in the order of 10^-9 C/cm^2°C. Higher figure of merit FM_RV, FM_RN and FM_RI values of the order 10^-14 CM/J. 10^-12 CM/J and l0^-11 CM/J respectively are observed in both Pr/Nd: BSNN compositions. Resistivity studies revealed a PTCR behavior.
