Dielectrics that provide higher electrostatic energy densities are urgently required for power electronic applications; recent observations in the solid solution of (1 - x)BaTiO 3 - xBiScO 3 show promise, and low temperature re-entrant dipole glass behavior is inferred. Here, direct observations of switchable polarization freezing in the reentrant dipole-glass (1 - x)BaTiO 3 - xBiScO 3, 0.1 ≤ x ≤ 0.4 are reported. As the temperature is decreased, the switchable polarization increases rapidly, reaches a maximum value at the reentrant temperature (T R) before disappearing at low temperatures. With measurement electric field (E), the T R is found to increase in (1 - x)BaTiO 3 - xBiScO 3, 0.1 ≤ x ≤ 0.4, as a function of x.
