摘要：
The methods of broadband dielectric spectroscopy are used to study the effect of substitution of Fe3+ by Sc3+ in Pb(Fe1-xScx)(2/3)W1/3O3 solid solutions of perovskite family on the dielectric response function in the frequency range from 120 Hz up to 100 THz (4 x 10(-9)-3 x 10(3) cm(-1)). The experimental data are analyzed in the framework of multiparameter dispersion models. The evolution of the dispersion parameters of absorption bands depending on the degree of cation substitution in the B position of perovskite basis of ABO(3) is discussed.
