Abstract :
This work presents electric-field-induced dielectric permittivity and depolarization in (001)-cut relaxor Pb(Mg1/3Nb2/3)0.70Ti0.30O3 (PMNT30%) and Pb(In1/2Nb1/2)0.70Ti0.30O3 (PINT30%) single crystals. The depolarization temperature Tdcong395 K of PINT30% is about 40 K higher than in the rhombohedral PMNT30%. The relaxor-type dielectric dispersion due to polar nanoclusters reappears above Td, and remains evident up to the Burns temperature.
