The various Aurivillius oxides, SrBi2-xLaxNb2O9 (x=0, 0.5), were synthesized by using the conventional solider state reaction method. Phase analyses were performed by X-ray diffraction (XRD) analyses and Raman spectroscopy. Microstructural morphology was investigated by scanning electron microscopy (SEM). The Curie temperature, maximum permittivity and activation energy decrease with the increase in La content.
