| dc.description.abstractEn | Perovskite types Ba<sub>1−<em>x</em></sub>La<sub><em>x</em></sub>Ti<sub>1−<em>x</em></sub>Fe<sub><em>x</em></sub>O<sub>3</sub> (with 0 ≤ <em>x</em> ≤ 0.15) ceramics have been prepared through a solid-state reaction route. The room-temperature X-ray diffraction study suggests that all the compositions have single phase. A broad dielectric anomaly coupled with the shift of dielectric maxima toward a higher temperature with increasing frequency indicates the relaxor-type behavior in some ceramics. The relaxor ceramics obtained obey the Vogel–Fulcher law. The partial replacement of Ba<sup>2+</sup> by La<sup>3+</sup> and Ti<sup>4+</sup> by Fe<sup>3+</sup> shows a remarkable decrease of <em>T</em><sub>C</sub>. The <em>P</em>–<em>E</em> hysteresis measurement proves the ferroelectric character of these compounds. The piezoelectric constant <em>d</em><sub>31</sub> of about 33.7 pC N<sup>−1</sup> was observed for Ba<sub>0.95</sub>La<sub>0.05</sub>Ti<sub>0.95</sub>Fe<sub>0.05</sub>O<sub>3</sub> ceramic. | |
