Investigations of the Phase Diagram of the PbTiO₃-BiFeO₃ System

Abstract

The phase diagram of the (Pb0.85Sm0.10)(Ti0.98Mn0.02)O3 - BiFeO3 system was studied by measuring the dielectric behavior as a function of temperature, coupled with room temperature XRD and measurements of d33, kt, and kp. A morphotropic phase boundary exists for between the tetragonal and rhombohedral phases for a BiFeO3 content of ≈55 mole%. Some of the studied compositions exhibit electromechanical properties suitable for transducer applications.
