| Abstract: | The electrostriction constant γ(m2V?2) of a uniaxial ferroelectric with a second order phase transition has been calculated as a function of the dielectric constant (?P/?E)0. The results have been experimentally verified on triglycine sulphate (TGS) by measuring γ and (?P/?E)0. A sign reversal of γ above the Curie temperature is presented. |
