Abstract
Harmonic analysis of the dielectric hysteresis loops near the phase transition temperature Tc obtained under application of harmonic electric field with intensity above the intensity of the coercive field is presented. It is shown that, the direction of polarization reverses when the field value satisfies condition Ec =Em sin ϕ0. The increase in E c while approaching Tc is shown to be the reason for the anomalous temperature independent behavior of E coer.
