| We present Ba/Co co-doping effects on BiFeO3 structure, optical, ferromagnetic, and ferroelectric properties at room temperature. XRD indicates a high distortion of the rhombohedral symmetry, confirmed by Raman spectroscopy, where a change in the intensity ratio of E-1/A1-1 vibrational modes is a result of the partial substitution of Fe3+ by Co3+. This induces an A-site disorder in the FeO6 octahedra. Co2+ acts as grain growth inhibitor reducing average grain sizes from 304 nm (without cobalt) to 200 nm (with cobalt) after sintering. The magnetization results show that the Co-cation impregnated samples have higher magnetization (31%) than doped and undoped samples. | |
