The effects of Sr-substitution in BaSmTiNbO ceramics: structural study, optical properties, and complex impedance spectroscopy.

Ceramics of (BaSr)SmTiNbO, denoted as BSSTN ( = 0, 0.25 and 0.5), were synthesized by the conventional solid-state reactions route.

Effect of sodium substitution by yttrium on the structural, dielectric and electrical properties of BaNaYNbO ceramics.

The effects of Na substitution by Y on the structural, microstructural, dielectric and electrical properties of BaNaYNbO compositions with (x = 0, 0.02 and 0.04) have been studied in detail.

Structural, electrical, and dielectric study of the influence of 3.4% lanthanide (Ln = Sm and La) insertion in the A-site of perovskite BaLnTiZrO.

This paper presents a systematic study of the substitution effect by lanthanides (Ln = Sm and La) in the A-site of perovskite BaLn(TiZr)O 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.
