Grain size-independent dielectric and ferroelectric properties of superparaelectric Mn–Nb co-doped barium titanate ceramics
Abstract
<jats:title>Abstract</jats:title><jats:p>The crystal structure, microstructure, dielectric and ferroelectric properties of polycrystalline BaTi<jats:sub>(1–2<jats:italic>x</jats:italic>)</jats:sub>Mn<jats:sub>(<jats:italic>x</jats:italic>)</jats:sub>Nb<jats:sub>(<jats:italic>x</jats:italic>)</jats:sub>O<jats:sub>3</jats:sub> (<jats:italic>x</jats:italic> = 0.05 and 0.06) with different grain sizes were investigated. All the ceramics exhibited pseudo-cubic symmetry at RT. The ceramics with <jats:italic>x</jats:italic> = 0.05 and 0.06 exhibited different trends of grain sizes, which were measured as 29.1 and 37.5 <jats:italic>μ</jats:italic>m for the ceramic with <jats:italic>x</jats:italic> = 0.05 and 2.1, 2.6, 3.2, and 4.9 <jats:italic>μ</jats:italic>m for the ceramic with <jats:italic>x</jats:italic> = 0.06. The ceramic with <jats:italic>x</jats:italic> = 0.05 exhibited grain size-dependent electrical properties, possibly because the phase transition temperature depended on the grain size due to the presence of long-range order in its temperature profile. Almost grain size-independent electrical properties were exhibited by the ceramic with <jats:italic>x</jats:italic> = 0.06, which was attributed to its superparaelectric nature where the phonon propagation length was expressed by its critical chemical grain size, thus, governing its properties.</jats:p>
