The evolution of switching polarization (P-r(s)) suppression, in Pb(Zr,Ti)O-3 films, induced by two different electric treatments is addressed in terms of the nonlinear dielectric response. The ac electric field dependence of dielectric permittivity was co ...

Relaxor Pb(Mg1/3Nb2/3)O3(PMN) and its solid solutions with ferroelectric PbTiO3 (PT) are of considerable interest from both the applications and the scientific point of view. In the past, many attempts were made to prepare and study the properties of these ...

A phenomenological model was proposed which describes frequency dispersion of nonlinear dielectric response of relaxer ferroelectrics (relaxors) as a result of dispersion of their linens dielectric permittivity. The model was applied to Pb(Mg1/3Nb2/3)O-3 ( ...

The non-linear dielectric properties of single crystals of PbMg1/3Nb2/3O3 relaxer ferroelectric were investigated experimentally by using measurements of the dielectric permittivity of this material as a function of the DC bias and the AC driving fields. T ...
A possible anomaly in the temperature dependence of nonlinear dielectric susceptibility chi(nl) of relaxor ferroelectrics related with the freezing phase transition was investigated. First, based on the phenomenological approach, the anomaly in the chi(nl) ...
The dielectric and piezoelectric response of ferroelectric thin films and ceramics was investigated as a function of the driving field amplitude. Detailed analysis of the amplitude and phase angle of the third harmonic of the dielectric displacement and pi ...
The dielectric response of the relaxer ferroelectric PbMg1/3Nb2/3O3 (PMN) is found to be a non-analytical function of the ac field, with the absolute value of the non-linear component of the polarization given by \P-nl\ alpha E-m(gamma(omega,T)). The depen ...
The impact of electrode-adjacent passive layers on the small signal dielectric response of a ferroelectric film containing a 180degrees-domain pattern has been analyzed. It is shown that, for a realistic physical situation, the so-called "in-series capacit ...
