Fortified relaxor ferroelectricity of rare earth substituted 4-layered BaBi_3.9RE_0.1Ti₄O₁₅ (RE = La, Pr, Nd, and Sm) Aurivillius compounds.

ABSTRACT: In this report, the effect of rare-earth (RE³⁺) ion substitution on structural, microstructural, and electrical properties in barium bismuth titanate (BaBi₄Ti₄O₁₅) (BBTO) Aurivillius ceramics has been investigated. The Rietveld refinements on X-ray diffraction (XRD) patterns confirm that all the samples have an orthorhombic crystal system with A2₁am space group. Meanwhile, temperature dependent synchrotron XRD patterns reveal that the existence of dual phase in higher temperature region. The randomly oriented plate-like grains are experimentally strived to confirm the distinctive feature of bismuth layered Aurivillius ceramics. The broad band dielectric spectroscopic investigation signifies a shifting of ferroelectric phase transition
