Roze, BiFeO3 is a particularly horrible example for a ferroelectrics neophyte.
You should look into better behaved (at least within DFT) materials, such as PbTiO3 or BaTiO3, first, before you can approach BiFeO3 with confidence. Second, you should elaborate on the "ferroelectric properties" that you have in mind. I can think of ten different things related to ferroelectricity: some of these could be probed with DFT and others could not. Finally, you should not forget to include your full affiliation when you are addressing this forum.
