摘要：

The influence of post-sintering annealing on the dielectric relaxation behavior was studied in (Sr1-1.5xLax)TiO3 in the temperature range of 1.5-300 K. The results show that the dielectric permittivity peaks with frequency dispersion can be gradually and absolutely eliminated by annealing in an oxidizing atmosphere, and recovered by annealing in a reducing atmosphere; this implies that these anomalies are closely related to oxygen vacancies.
