摘要：

The frequency-domain dielectric spectra of ceramic SrFeO3-x have been measured over wide temperature (100-300 K) and frequency (5 Hz-13 MHz) range. The results have been related to the defect ordering in this compound. The loss peak behavior results from a relaxation process has been identified for the "disordered" sample, while the anomalous low-frequency dispersion have been observed in the "ordered" sample.
