Abstract

Electrical conductivity of composites material LaFeO3.xFe3O4 with x = 0.0, 0.1, 0.2, 0.3, and 0.4 have been studied by impedance spectroscopy method. LaFeO3 was synthesized by sol-gel method result in nanoparticle, then it mixed with Fe3O4 powder, homogeneously. The mixture was pressed into pellet and sintered at 1300 °C for 1 h to form LaFeO3.xFe3O4 composites materials. The electrical properties as a function of temperature (300 K - 500 K) and frequency (100 Hz - 1 MHz) were presented in Nyquist and Bode plot. From these plots, the equivalent circuit was found and their parameters are contributed by grain and grain boundary which is supported by morphology characterized by scanning electron microscopy (SEM). DC conductivity of LaFeO3.xFe3O4 as a function of temperature was explained by using Arrhenius equation of 1000/T vs ln σ. From this equation, the values of the activation energy (Ea) for all samples were calculated. The value of Ea can be also analyzed as grain and grain boundary contribution.
