Abstract
The dielectric properties of Pb(Zn1/3Nb2/3)O3-PbZrO3-PbTiO3 (PZN-PZ-PT) system near morphotropic phase boundary (MPB) are studied in this paper. It is found that, for the samples with tetragonal symmetry, a spontaneous normal ferroelectric—relaxor phase transition exists in temperature lower than that of permittivity peak.
