Abstract
The 0.6BiFeO3–0.4(Bi0.5Na0.5)(1−x)Ba x TiO3 (short for BF-BN(1−x)Ba x T) (x = 0, 0.2, 0.3, 0.4, 0.5) solid-solution ceramics were fabricated by a sol–gel method. The presence of constituent phases in ceramics was investigated by X-ray diffraction. It indicates that all of the samples are single phase. Not only that, it also proves the rhombohedral structure of the samples. Multiferroic properties dependent on the doping content of Ba ions were studied systematically. The ferroelectricity and ferromagnetism were tested, displaying the maximum values of remnant polarization and remnant magnetization at x = 0.4 simultaneously. With the increasing in x, the peak of dielectric constant depending on temperature shifts toward to the lower temperature range. In addition, the dielectric diffuse degree also increases monotonically as x increases to 0.5.
