Abstract
The mixed-type rotation model around the a- and the c-axes for the molecular rotation of the NO2 radicals in Sodium nitrite is discussed. There found an intermediate state during the a-axis rotation that can explain some experimental results. The mechanism of polarization reversal can be explained by this model, and the transition temperature is estimated as 341 K by using Ising model.
