AbstractRecent experiments revealed unusual dielectric behaviors of Pb(Mg 1/3Nb 2/3)O 3 originated from polar nanoregions (PNRs). Thus, Pauli's master equation is adopted to investigate the distinct dielectric responses, correlation strength, and volume evolutions of static and dynamic PNRs. Our findings have not only validated the percolation theory but also ascertained Lorentzian distribution of the rate of thermal change of PNR volume. Finally, based on Maxwell's equation the observed dielectric deviations of bulk permittivity from Curie-Weiss law are attributed to the thermal effects on static volume fraction and polarization rotation. © 2011 American Institute of Physics.
