Abstract
PbCi(1/3)Nb(2/3)O(3) at high pressure and temperature is found to exhibit t he phase transition from pyrohlore structure to perovskite one. Results of the weak-field dielectric response investigations are given, The temperatur e phase transition is shown to be due to change of character of dipole orde ring for both structure modifications. For perovskite modification it corre sponds to relaxer ferroelectric type.
