Debye-Waller Factor Order-disorder displacive Type Sodium Nitrite Structure Analysis Least Squares Calculation Maximum Entropy Method
In order to understand the relation between the transition mechanism and the thermal vibration, the temperature dependence of the Debye-Waller factor is investigated in NaNO_2 by single-crystal X-ray diffractometry. The crystal parameters are refined by least squares calculations both in paraelectric and ferroelectric phases. The maximum entropy method is also employed to estimate the spontaneous polarization. The Debye-Waller factor displays a minor anomaly at the order-disorder transition point. The result is compared with K_2SeO_4, a typical displacive crystal.
