Presented here are the results of measurements of the effect of pressure and temperature on the values of exponents φ and K defined as follows: The magnitude δϵ/E 2 is a measure of the nonlinear dielectric effect (NDE). The nature of the amplitude variations is also shown. Tests were conducted on a nitrobenzene-hexane solution of critical concentration x c = 0.43 mole fraction of nitrobenzene, for which the curve T c(p) describing the variations of critical temperature has been plotted for a wide range of pressures.read more

Kerr effect and the nonlinear dielectric effect on approaching the critical consolute point.
TL;DR: For the exponent ψ which describes a critical anomaly of the nonlinear dielectric effect (NDE) and the electro-optic Kerr effect (EKE) in critical solutions, theoretical models predict: ψ NDE = ψ EKE =ψ theor =γ-2β as mentioned in this paper.

Droplet model for the analysis of the dielectric properties of critical binary mixtures
TL;DR: In this paper, the dielectric behavior of binary mixtures in the vicinity of a consolute critical point was investigated. And the results showed that along the critical isochore, one may expect the static permittivity eE(T) to remain finite but to exhibit a cusp, whereas the nonlinear dielectrics effect, the Kerr effect, and the Cotton-Mouton effect all diverged strongly with the universal exponent Ψ=2γ−dν.
