Abstract
Introduction of graphene in the Bi 2 O 3 -Fe 2 O 3 system has been found to facilitate the formation of perovskite phase of BiFeO 3 (BFO). The room temperature XRD pattern shows that the formation of BiFeO 3 (BFO) and also its composite with graphene has started at a sintering temperature as early as 300 0 C. Both XRD and FESEM of the sintered sample has shown that the addition of graphene has a marked effect on both the structure and microstructure of BiFeO 3 (BFO). Micro Raman spectra shows intensity ratio of 2D to G is around 1 indicating the presence of graphene as bi-layer in composite even upto a sintering temperature of 600 0 C. The graphene flaky nature with stacking of layers and sheet like folds having randomly orientation morphology has been confirmed from the TEM of the composite. So, an enhanced multiferroic properties has been envisioned due to the presence of π conjugate carbon network in the BFO matrix.
