Broadband dielectric spectroscopy results of various ordered and disordered (1x)Pb(Mg 1/3 Nb 2/3 )O 3 -(x)Pb(Sc 1/2 Nb 1/2 )O 3 (PMN-PSN) ceramics are investigated in the temperature range from 80 K to 300 K and frequency range from 20 Hz to 2 THz. Dielectric dispersion is very broad and in the ferr
Pb(Sc~ ~Tal \_,)O~ ceramics have been characterized by dielectric measurements in a wide range of frequencies (10 2-10'; Hz). A strong dispersion occurs with two low and high frequency contributions below the transition temperature. Only high frequency relaxation is still observed at high temperatur
