Abstract
SmBi5Fe2Ti3O18, a five layered bismuth oxide compound is synthesized u sing a solid-state double sintering method. DC conductivity, impedance , and AC conductivity are studied in the temperature range 30-500 degr ees C and frequency range 1 kHz-1 MHz. Complex impedance plots are use d to separate grain and grain boundary contributions to electrical imp edance. Activation energy for DC conductivity was found to be around 1 .0 eV. The results are analyzed to understand the conductivity mechani sm.
