Title: A note on structural and dielectric properties of BiFeO{sub 3}- PbTiO{sub 3} and BiFeO{sub 3}- PbZrO{sub 3} composites

The composites of BiFeO{sub 3}-PbTiO{sub 3} (BF-PT) and BiFeO{sub 3}-PbZrO{sub 3} (BF-PZ) were prepared by mixed oxide method. Room temperature X-ray diffraction data confirms the rhombohedral and tetragonal crystal structure respectively. Dielectric constant of BF-PZ is found to give high value compared to BF-PT and hence, there is an increase value of ac conductivity for the former. Both the composites show negative temperature coefficient of resistance (NTCR) behavior. The activation energies of BF-PT and BF-PZ are found to be 0.35 eV and 0.53 eV respectively. The d{sub 33} coefficients are found to be 2.0 and 2.1 pC/N for BF-PT and BF-PZ respectively.
