Abstract

Ba(Sc$^{3+}$, Sb$^{5+})_{\mathrm{y}}$Ti$_{0.90}$O$_{3}$, with y $=$ 0.05 and 0.10, is investigated through temperature dependent electrical and structural characterization. The material is electrically characterized from 10 Hz to 2MHz for dielectric constant, tunability, dissipation factor and figure of merit over the temperature range of -50 $^{\circ}$C to 125 $^{\circ}$C. In addition, lattice parameters and structural changes of the material are reported as a function of temperature as obtained using x-ray diffraction and Rietvield refinement. Properties of these electric-field tunable materials are discussed in terms of ferroelectrics, non-relaxor versus relaxor behavior, and a ferrorelectric dipole-like glass state.
