Description

We calculate the field-dependent susceptibility χ(E,T) of disordered dielectrics with dipole impurities of KTaO3:Li and KTaO3:Nb. The calculations had been carried out in the framework of our random field method. The fair coincidence between theory and experiment shows that our theory can describe the main peculiarities dependence of the observed nonlinear dielectric susceptibility as a function of temperature, electric field, and concentration
