Ni-doped BiFeO₃ powders with the composition BiFe_1-xNi_xO₃ (x = 0.05, 0.1 and 0.15) were prepared by a self-propagating high-temperature synthesis (SHS), using metal nitrates as oxidizers and glycine as fuel. The X-ray diffraction (XRD) patterns depict that Ni-doped BiFeO₃ ceramics crystallize in a rhombhohedral phase. The scanning electron micrographs of Ni-doped BiFeO₃ ceramics show a dense morphology with interconnected structure. It is found that, the room-temperature magnetization measurements in Ni-incorporated BiFeO₃ ceramics give rise to nonzero magnetization. The magnetization of Ni-doped BiFeO₃ ceramics is significantly enhanced when Ni doping concentration reaches to x = 0.1 at 5 K. The variations of dielectric constant with temperature in BiFe_0.95Ni_0.05O₃, BiFe_0.9Ni_0.1O₃ and BiFe_0.85Ni_0.15O₃ samples exhibit clear dielectric anomalies approximately around 450 ℃, 425 ℃ and 410 ℃ respectively, which correspond to antiferromagnetic to paramagnetic phase transition of the parent compound BiFeO₃.
