Abstract

The nonlinear dielectric response in [001] and [111] (1-x) Pb (Zn13 Nb23) O3 -x PbTiO3 (x=0.045 and 0.08) single crystals was investigated as a function of frequency between 30 and 250 °C. For comparison, a parallel study was carried out on a BaTiO3 single crystal. Both second and third harmonic polarization components were detected in Pb (Zn13 Nb23) O3 -PbTiO3 and BaTiO3 single crystals, and were observed to go through maxima at the phase transition temperatures. The third harmonic signal was nearly frequency independent for BaTiO3, but strongly dispersive in Pb (Zn13 Nb23) O3 -PbTiO3. The strong frequency dependence appears to be characteristic of some relaxor substructure of the domains.
