Abstract: Through this report, we intend to highlight the effect of R3c phase in the BiFe1-xCoxO3: x=33, 34. Study of impedance and modulus spectra points towards lower activation energy of resistance as compared to capacitance relaxation, as the cause for finite conductivity at near and above room temperature. Magnetodielectric study shows decrease in its value by half, because of absence of R3c phase in the sample. Due to absence of R3c phase, the activation energy of capacitance relaxation is also found to increase by three times. It thus shows that R3c phase is very important for having capacitance relaxation in this sample system.
