Dielectric, elastic, piezoelectric, electro-optic, and elasto-optic tensors ofBaTiO3crystals

Abstract

The complete set of material parameters of a top-seeded solution-grown ${\mathrm{BaTiO}}_{3}$ crystal has been determined by numerically evaluating available measurements and using additional measurements presented in this work. The parameters were determined at room temperature and consist of the low-frequency clamped dielectric constants ${\mathrm{\ensuremath{\epsilon}}}_{\mathit{i}\mathit{j}}^{\mathit{S}}$, elastic stiffness constants at constant electric field ${\mathit{c}}_{\mathit{i}\mathit{j}\mathit{k}\mathit{l}}^{\mathit{E}}$, piezoelectric stress coefficients ${\mathit{e}}_{\mathit{i}\mathit{j}\mathit{k}}$, elasto-optic tensor at constant electric field ${\mathit{p}}_{\mathit{i}\mathit{j}\mathit{k}\mathit{l}}^{\mathit{E}}$, and clamped electro-optic coefficients ${\mathit{r}}_{\mathit{i}\mathit{j}\mathit{k}}^{\mathit{S}}$.
