Structural, electrical, and dielectric study of the influence of 3.4% lanthanide (Ln³⁺ = Sm³⁺ and La³⁺) insertion in the A-site of perovskite Ba_0.95Ln_0.034Ti_0.99Zr_0.01O₃.

ABSTRACT: This paper presents a systematic study of the substitution effect by lanthanides (Ln³⁺ = Sm³⁺ and La³⁺) in the A-site of perovskite Ba_(1-x)Ln_2x/3(Ti_0.99Zr_0.01)O₃ with a substitution rate equal to 3.4%. All samples were synthesized by the classical solid-state reaction route and characterized by X-ray diffraction and a complex impedance spectroscopy technique. The synthesized compounds exhibit single-phase perovskite structures without detectable secondary phases. The P4mm space group was verified by the Rietveld method from the X-ray diffraction data, with the tetragonal distortion decreasing with the increasing ionic radius of the lanthanides.
