| Abstract: | The influence of bias and variable electric fields on the dielectric response of the K0.91(NH4)0.09H2PO4 single crystal has been studied in the vicinity of the ferroelectric phase transition temperature T C. Below T C, the nonlinear response is caused mainly by the domain mechanism. This is confirmed, in particular, by observations of chaotic oscillations in a series RLC-circuit containing the studied sample as a capacitor C and excited by a sinusoidal voltage. Peculiarities of the behavior of the dielectric nonlinearity are found near the Curie temperature, which are explained by the emergence of an intermediate heterophase state. |
