Electrical and Structural Characterization of Ba(In,Sb)$_{y}$Ti$_{1-2y}$O$_{3}$ With y $=$ 0.05 and 0.10*

Ba(In,Sb)$_{0.05}$Ti$_{0.90}$O$_{3}$ and Ba(In,Sb)$_{0.10}$ Ti$_{0.80}$O$_{3}$ are investigated through temperature dependent electrical and structural characterization. The material is electrical characterized from 10 Hz to 2 MHz for dielectric constant, tunability, dissipation factor and figure of merit over the temperature range -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 Rietveld refinement. Properties of these electric-field tunable materials are discussed in terms of ferroelectrics, non-relaxor versus relaxor behavior, and a ferroelectric dipole-like glass state.
