Structural and spectroscopic characterization of bismuth-ferrites

Abstract

BiFeO3 based materials are currently one of the most studied multiferroics due to their possible applications at room temperature. In this study two sets of BFO are synthesized at different sintering temperatures i.e. BFO-1 and BFO-2, synthesized at a calcination temperature of 650° C and sintering temperature of 750° C and 820° C respectively. The structural characterization is studied using XRD. BFO-2 which is sintered at a temperature of 820° C shows much better properties as well as rhombohedral structure in comparison to the hexagonal counterpart in case of BFO-1. In addition to this the spectroscopic diagnosis using FTIR and Raman spectroscopic techniques are also highlighted here.
