采用标准固相反应法制备了Bi1−xNdxFeO3单相多晶样品。记录和分析了粉末样品的X射线衍射图，以确定其晶体结构和晶格参数。此外，利用红外光谱技术对这些样品进行了表征，以识别和了解当前样品中的成键方面。在室温下对样品进行了介电测量，测量范围为100 Hz-1 MHz，在某些固定频率下也测量了300-750K温度范围内的介电性能。为了了解样品的导电机理，对样品的直流和交流电阻率进行了研究。
Single-phase polycrystalline samples of Bi1−xNdxFeO3were prepared by standard solid state reaction method. X-ray diffraction (XRD) patterns of the powder samples were recorded and analyzed for the confirmation of crystal structure lattice parameters. Further, these samples were characterized by IR technique to identify and understand the aspect of bonding in the present samples. The dielectric measurements were carried out on the samples as a function of frequency in the range 100Hz to 1MHz at room temperature and also as a function of temperature in the range 300–750K at certain fixed frequencies. The DC and AC electrical resistivity studies were carried out in order to understand conduction mechanism in the samples.
