Abstract

Dielectric properties of ceramic samples of a 0.85SrTiO3-0.15KTaO3 solid solution have been studied. The temperature dependence of the dielectric permittivity exhibits maxima with a strong frequency dispersion, which is described by the Vogel-Fulcher law with a characteristic temperature T g=26 K. These features are apparently connected with transition to a polar glasslike state.
