Popis: | This paper studies the dielectric spectra of solid solutions (SS) of the system (1 − x − y)NaNbO3–[Formula: see text]KNbO3 –[Formula: see text]CdNb2O6 [Formula: see text]= 0.075, [Formula: see text]= 0.05 ÷ 0.30 in the temperature range (10 ÷ 900) K. The formation of a local maximum was established in the interval (260 ÷ 300) K at small [Formula: see text] values, which, as KNbO3 increases, is gradually blurred and becomes an inflection point. Detected in SS with [Formula: see text] = 0.05 ÷ 0.10, the shift of the maxima of dependences [Formula: see text]′/ [Formula: see text]0([Formula: see text]) and [Formula: see text]′′/[Formula: see text]0 ([Formula: see text]), depending on the frequency of the electric field at the temperature ranges (300 ÷ 304) K and (258 ÷ 271) K, is not related to relaxation. This anomaly may indicate a crystallographic disorder to A and B positions. The conclusion is made about the expediency of using the obtained results for the development of functional ferroactive materials. |
