Abstract

This work presents electric-field-induced dielectric permittivity and depolarization in (001)-cut relaxor Pb(Mg_1/3Nb_2/3)_0.70Ti_0.30O₃ (PMNT30%) and Pb(In_1/2Nb_1/2)_0.70Ti_0.30O₃ (PINT30%) single crystals. The depolarization temperature T_dcong395 K of PINT30% is about 40 K higher than in the rhombohedral PMNT30%. The relaxor-type dielectric dispersion due to polar nanoclusters reappears above T_d, and remains evident up to the Burns temperature.
