Multiferroic materials, which simultaneously exhibit ferroelectricity and ferromagnetism, have recently stimulated a sharply increasing number of research activities for their scientific interest and significant technological promise in the novel multifunctional devices. Natural multiferroic single phase compounds are rare, and their magnetoelectric response are relatively weak at room temperature. In contrast, multiferroic composites improve the magnetoelectric coupling at room temperature which can have potential applications in data storage, sensors, spintronics and filters. In view of this, Multiferroic BiFeO3 –BiCoO3 (BF-BC) composite thin films have been prepared by the spray pyrolysis method, where (110) - oriented texture was obtained. X-ray diffraction analyses confirmed that BF-BC composite films were highly (110) textured. The AFM images show that the films were uniform, dance and of nearly spherical shape nanoparticle with size of 18 nm. The (110) - texture BF-BC composite films exhibits improvement in remanent polarization and coercive field with very low leakage current. The optical properties of the composite films have been studied and correlated with their structural parameters.
