Parameter of dielectric loss distribution in the new model for complex conductivity based on Havriliak–Negami formula

This paper is focused on the comparison of the results of various approximation models describing the frequency dependences of the dielectric constant [Formula: see text] and [Formula: see text], the tangent of the loss angle tg[Formula: see text] and the electrical conductivity [Formula: see text] and [Formula: see text] of nonlinear dielectrics. The classic ferroelectric material of the PZT system with [Formula: see text] was chosen as the...
