Abstract

In this paper we present dielectric spectroscopy results of NBT-(0.6-x)ST-xPT with x = 0.2 solid solution. Dielectric investigations clearly showed a relaxor - normal ferroelectric phase transition at T _PT = 419 K and low temperature and low frequency dispersion similar to coexistence of dipolar glass and ferroelectric phase. The mean relaxation time above the phase transition follows Vogel - Fulcher law with following parameters: E _A = 0.179 eV, τ ₀ = 3.39.10 ^-14 s, T _VF = 223 K.
