Abstract:The concentration dependence of the ferroelectric transition temperature Tc of single crystals of the solid solution tris-sarcosine calcium chloride1?x bromidex is studied experimentally by measurement of the static dielectric constant ?b and described by the empirical relation Tc(X) = Tc(0) 1?(X/Xc)]12. The Ising model with transverse field and the model of coupled anharmonic oscillators are used to explain the concentration dependence of the transition temperature Tc.
