Abstract

The normal-incommensurate phase transition of K₂ZnCl₄ and [N(CH₃)₄]₂ZnCl₄ were studied by the linear birefringence method for the determining critical exponent, β. The critical linear birefringence behavior can well be described by standard 3-d XY model over the temperature range 10^-3 < (T_i - T)/T_i < 10^-2. The effect of symmetry breaking was not found in both K₂ZnCl₄ and [N(CH₃)₄]₂ZnCl₄. So we can determine the critical exponent β directly from linear birefringence by scaling analysis. As the temperature was decreased in K₂ZnCl₄ the critical linear birefringence behavior asymptotically approach to the prediction of classical mean field theory.
