Influence of the prehistory of NaNbO3-Gd1/3NbO3 ceramics and single crystals on their dielectric properties

摘要

The dielectric properties of a ceramic and a single crystal of the same composition 0.9NaNbO(3)-0.1Gd(1/3)NbO(3) (NNG10) with different prehistories of the material are investigated in the low- and infralow- frequency ranges. It is revealed that the dielectric among of the material based on the NaNbO3 antiferroelectric with a smeared phase transition differs in character from similar phenomena observed in relaxor ferroelectrics.
