Abstract

A phenomenological thermodynamic potential was constructed based on the properties of bulk BaTi O3 single crystals. An eighth-order polynomial of Landau-Devonshire expansion was employed. It reproduces bulk properties including the three possible ferroelectric transition temperatures and their dependence on electric fields, as well as the dielectric and piezoelectric constants. Different from the existing thermodynamic potential, it is applicable to predicting the ferroelectric phase transitions and properties of BaTi O3 thin films under large compressive biaxial strains.
