Abstract
The permittivity spectra of solid solutions (1–x)SrTiO3–xDyScO3 (x = 0, 0.01, 0.03) and ceramic samples of strontium titanate doped with Sc3+ ions have been studied in the frequency range from 10 Hz to 1MHz. It has been found that the permittivity exhibits maxima at cryogenic temperatures, and the dielectric relaxation processes are observed in the temperature ranges of 60–100 and 170–300 K. The characteristic parameters of these processes have been determined. It has been shown that a linear dependence of the polarization on an applied electric field, which is characteristic of conventional dielectrics, is observed in the studied compositions in the temperature range of the dielectric anomalies.
