Wide band dielectric spectroscopy was applied from kHz to THz region for the analysis of both the ionic and the dipole polarization in Ba_(0.6)Sr_(0.4)TiO_3 ceramics. The dielectric permittivity above the dielectric maximum temperature (T_m) is mostly dominated by the ionic polarization, while that below T_m is governed by the dipole polarization. Dielectric permittivity given by the dipole polarization increased and the relaxation frequency decreased with decreasing temperature. These phenomena are related to a increase of the size of polar nanoregions (PNRs).
