Synthesis and structural characterization of BiFeO3-BaTiO3 materials

BiFeO3 material shows simultaneous ferromagnetic and ferroelectric behavior, therefore their is research interest in such materials for novel bi-functional devices. The partial substitution of Ba and Ti ions at Bi and Fe sites may affect the functional properties of the parent BiFeO3 material. Substituted BiFeO3 material with similar type of materials such as BaTiO3 and Bi4-x NdxTi3O12 were synthesized and characterized by x-ray diffraction and Raman spectroscopy. Single phase thin films is achieved solution route for the composition x < 0.5. The BiFeO3 films showed weak ferroelectric polarization P-r = 2.2 mu C/cm(2) and BiFeO3 - Bi3.44Nd0.56Ti3O12 films also showed improved ferroelectric polarization P-r = 10 mu m/cm(2) good saturation field.
