摘要

A critical behavior of dielectric susceptibility has been discovered in relaxor ferroelectric 0.75Pb(Mg_1/3Nb_2/3)O₃-0.25PbTiO₃. The real part of permittivity ε′ was found to follow the relation ε′ - ε_x = χ′ ∝ (T-T₀)^-2 at T>T₀, and ε′ ∝ (T_c-T)^-1 at T<T_c, where T₀≈T_c<T_m; T_m is the temperature of the diffused ε′(T) maximum as is typical of relaxors; ε_x is the frequency-independent parameter, and x′ is the susceptibility depending on frequency via the "universal" relaxation law χ′ ∝ f^n-1 The susceptibility χ′ is suggested to originate from the polarization of polar nanoclusters.
