Abstract

Results of polarization and polarization switching in samples prepared by solid phase synthesis of the (1-х)(K_0.5Na_0.5)(Nb_0.93Sb_0.07)O₃–xBaTiO₃ + 0.5mol%MnO₂ system at x = 0.01, 0.02, and 0.04 (KNNS7–xBT) studied over a wide range of temperatures are reported. The observed features of the dielectric nonlinearity at the ferroelectric and structural phase transitions in the materials are described. The dielectric response data of the samples of different contents of the admixture in the KNNS7–xВT ceramics are compared with the behaviour of their elastic properties.
