- Abstract
- We have prepared BiFe0.95Ni0.05O3 by the standard solid-state reaction and rapid sintering. The structural analysis by x-ray diffraction for BiFe0.95Ni0.05O3 shows rhombohedral perovskite structure (R3c), and lattice constants a and c of BiFe0.95Ni0.05O3 are slightly increased as compared to those of BiFeO3. The Raman studies present the increase of oxygen vacancy by the Ni2+ substitution. The magnetic properties of BiFe0.95Ni0.05O3 are greatly improved, owing to the enhanced ferromagnetic interaction caused by the Fe/Ni coupling. BiFe0.95Ni0.05O3 sample is ferromagnetic with a cluster-glass state unlike the antiferromagnetic BiFeO3-based compounds. (C) 2013 AIP Publishing LLC.
