Title: Structural, vibrational and dielectric studies of (0.95)Pb(Zr{sub x}Ti{sub 1−x})O{sub 3}-(0.05)BiFeO{sub 3} nanoceramics

(0.95)Pb(Zr{sub x}Ti{sub 1−x})O{sub 3}-(0.05)BiFeO{sub 3} nanoceramics with x=0.51, 0.53 and 0.55 were synthesized by sol-gel route. Rietveld refined X-ray powder diffraction pattern of the samples confirm the single phase formation of compounds with tetragonal structure (P4mm). FT-IR studies revealed that slight shift of phonon modes towards the lower wave number and increase in the bond length with increasing Zr{sup 4+} concentration. Room temperature dielectric properties of system revealed that relaxor characteristics of these samples. Ferroelectric hysteresis curve shows the decrease in polarization values with Zr concentration.
