This paper provides a review of a systematic micro‐Raman scattering study on various lead‐
and barium‐based ABO3 perovskites (A= Pb, La, Ba, Sr, Ce, Gd, Nd and B= Ti, Zr) …

A giant electrocaloric effect (ECE) near room temperature is reported in a lead‐free bulk
inorganic material. By tuning Ba (ZrxTi1–x) O3 compositions which also exhibit relaxor …

In this study, the phase transition behavior of the BaTiO 3–BaZrO 3 system was studied
using micro-Raman scattering and dielectric measurement techniques. BaZr x Ti 1− x O 3 …

Lead free piezoelectric ceramics barium zirconate titanate–barium calcium titanate,[xBZT–
(1− x) BCT](0.48≤ x≤ 0.52), were synthesized by sol–gel method. Calcination of the as …

Nowadays, perovskite materials are well known for electronics and optoelectronics
applications. We have investigated a potential candidate for those applications to compare …

Lead‐free (Ba1− xCax)(Ti0. 95Zr0. 05) O3 (x= 0.02–0.20) ceramics were prepared
