Frequency dependence of the phase transition in Pb(Mg1/3Nb2/3)O-3-PbTiO3 relaxor ferroelectrics

Abstract

To understand the frequency dependence of phase transitions and related physical properties of Pb(Mg1/3Nb2/3)O-3-based relaxer materials, the dielectric constants, electric-field-induced polarization, and pyroelectric depolarization are studied under varying temperatures and measuring frequencies. A linear relationship between the transition temperature and the logarithm of frequency is experimentally observed. (C) 1997 American Institute of Physics.
