Abstract

We propose an order-disorder type microscopic model for BaTiO $_3$ -like Ferroelectric Substance. Our model has three phase transitions and four phases. The symmetry and directions of the polarizations of the ordered phases agree with the experimental results of BaTiO $_3$ . The intermediate phases in our model are known as an incompletely ordered phase, which appears in a generalized clock model.
