Abstract
A La1.4Sr1.6Mn2O7 compound is fabricated in this study by standard solid state reaction method to determine its conduction properties by combining grain boundaries and intrinsic magnetoresistance. X-ray diffraction analysis and complex impedance measurements are used to characterize the obtained samples. The results show that the grain contribution is almost independent of the bias voltage and indicate that the two-phase grain boundary has a predominant effect on the AC electrical transport of the compound.
