The interaction of multifold polar orderings in Ba-doped Sr&quot...

A series of polycrystalline Sr0.7-xCa0.3Ba xTiO3 (SCBT) (0.0 ≤ x ≤ 0.25) samples were synthesized through solid-state reaction method, and their microstructural, anti-ferroelectric (AFE), ferroelectric (FE), dielectric, and phase transition properties were investigated. With the incorporation of Ba2+ at Sr2+ site, the AFE polar phase (x = 0.0) has been sharply changed, experiencing AFE state, enhanced FE state, cooperative FE state, and normal FE state, owing to the competition and couplin
