The Mössbauer spectra of the system (PbTiO3)0.95(BiFeO3)0.05 have been studied from room temperature to 585°C. From the isomer-shift of 0.491±0.02 mmsec-1 at room temperature, the ionicity is found to be 60% ± 20%. A discontinuity in the plot of isomer-shift versus temperature at Tc is observed. The quadrupole splitting at room temperature is 0.295 ± 0.02 mm/sec-1. A dip in the Mössbauer fraction is observed at the Curie temperature.
