Multifunctional zinc oxide-bismuth ferrite material was developed as energy material. The ferrite material was developed by employing polycrystalline BiFeO3 and semiconductor ZnO via precipitation technique. The ZnO-BiFeO3 composite was characterized by X-ray diffraction, scanning electron microscopy-energy dispersive spectroscopy, and transmission electron microscopy, which show that BiFeO3 immigrated into the ZnO. Temperature dependent magnetic behavior of ZnO-BiFeO3 composite was studied by vibrating sample magnetometer (VSM) in the range 5 to 300K. As temperature increased, the magnetic nature decreased; exhibiting a blocking temperature at 50K. This nanocomposite system has potentials for spintronics and energy applications.
