摘      要：Ni-doped BiFeO_(3) powders with the composition BiFe_(1-x)Ni_(x)O_(3)(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 *** X-ray diffraction(XRD)patterns depict that Ni-doped BiFeO_(3) ceramics crystallize in a rhombhohedral *** scanning electron micrographs of Ni-doped BiFeO_(3) ceramics show a dense morphology with interconnected *** is found that,the room-temperature magnetization measurements in Ni-incorporated BiFeO_(3) ceramics give rise to nonzero *** magnetization of Ni-doped BiFeO_(3) ceramics is significantly enhanced when Ni doping concentration reaches to x=0.1 at 5 *** variations of dielectric constant with temperature in BiFe_(0.95)Ni_(0.05)O_(3),BiFe_(0.9)Ni_(0.1)O_(3) and BiFe_(0.85)Ni_(0.15)O_(3) samples exhibit clear dielectric anomalies approximately around 450℃,425℃and 410℃respectively,which correspond to antiferromagnetic to paramagnetic phase transition of the parent compound BiFeO_(3).
