- Abstract
BiFeO and BiNdFeO ceramics were prepared by co-precipitation method. The crystal structure and electrical properties of the samples were characterized by X-ray diffraction (XRD), impedance spectra and leakage current measurement. XRD result implied that the impurity phases are weakened by suitably doping Nd. The impedance spectra of BiFeO sample indicate that low grain boundary resistance and non Debye-type relaxation below the Néel temperature. Complex impedance spectra suggested that the doped samples are closer to Debye-type, and the grain boundary resistance increases which lead to low leakage current density.
