Abstract
A distinction between the behaviour of (Ba1-xSrx)TiO3samples with x ≤ 0.12 and x ≥ 0.16 is made on the basis of thermal hysteresis in the temperature dependence of the dielectric constant and the frequency dependence of the temperature at which the dielectric constant peaks. The scaling behaviour of the dielectric loss spectra for all the compositions suggests that the distribution of relaxation times is temperature independent. It is proposed that, for x ≤ 0.12 and x ≥ 0.16, the system is in a domain and dipolar glass state, respectively.
