Abstract

The results of the experimental study of the critical X-ray scattering (CS) in PbZr_0.6Ti_0.4O₃ (PZT40) single-crystal are presented. Temperature evolution of the CS lineshape and intensity was analyzed. It is demonstrated that CS can be described in terms of the mean-field model. Temperature dependences of the peak intensity of the CS, proportional to the static susceptibility, and the correlation length of the «ferroelectric fluctuations» follow the Curie-Weiss law with the Curie temperature T_c=638 K. Obtained results confirm the second-order character of the phase transition in the PZT40.
