ABSTRACT

A Bi2Mn2O7 ceramic sample was prepared by solid state reaction method. Its dielectric property was then characterized by impedance analysis within frequencies range from 102 Hz to 106 Hz and temperatures range from room temperature to 450°C. All spectrums were then normalized into a single master curve. The dielectric response mechanism observed in the sample master curve spectrum were modeled by combinations of diffusive, quasi-dc, bound charge (dipole-like) elements with a non-dispersive capacitor. The experimental data are in close agreement with the value obtained from equivalent circuit.
