The calculations reveal that at the optimized lattice volume BFO has a lower energy in ferromagnetic state as compared with antiferromagnetic state. At the equilibrium volume, BFO shows metallic behavior, however, under a large tensile strain ($\\sim25\\%$), BFO shows half-metallic behavior consistent with the integer magnetic moment of $4.0\\mu_{\\rm{B}}$/fu mainly caused by the $t_{2g}$ and $e_{g}$ electrons of Fe.
