摘要：

A model for the size dependence of the Curie temperature T-c of perovskite ferroelectric particles without any free adjustable parameters has been developed. The model predicts that T-c decreases with decreasing particle size. The predictions of the model are in agreement with experimental results for PbTiO3 and BaTiO3.
