采用复烧法制备了Ni掺杂的Bi4NdTi3Fe1−xNixO15(x=0.1，0.3，0.5和0.7)(Nix)陶瓷。Ni替代Fe并没有改变Bi4NdTi3FeO15(BNTF)的层状钙钛矿结构，只是在Ni0.7样品中出现了少量的Ni2O3。所有Nix样品都清晰地观察到具有Aurivillius化合物特征的片状颗粒形态。εr、2Prand 2Mr值与Ni掺杂浓度不成正比，而是先增大后减小。综合考虑铁电和磁性，在实验范围内获得了Ni0.3样品的最佳室温(RT)多铁性，并从磁性离子的半径差、磁性离子的比例以及不同磁性离子的位置等方面进行了初步的讨论。本工作对基于四层结构Aurivillius化合物的RT多铁材料的组成设计具有一定的指导意义。
Ceramics of Ni-doped Bi4NdTi3Fe1−xNixO15(x=0.1, 0.3, 0.5 and 0.7) (Nix) were synthesized by a multicalcination procedure. The substitution of Ni for Fe does not change the layered perovskite structure of Bi4NdTi3FeO15(BNTF) except that a small amount of Ni2O3appears in the Ni0.7sample. Plate-like morphology of the grains which is characteristic for layer-structure Aurivillius compounds was clearly observed for all the Nixsamples. Theεr, 2Prand 2Mrvalues are not proportional to the Ni doping concentration but increase firstly and then decrease. Taking into account ferroelectric and magnetic properties together the optimum room temperature (RT) multiferroic property was acquired in the Ni0.3sample within the range of experiment, which is preliminarily discussed from the radius difference of magnetic ions, their ratio and the location of different magnetic ions. The present work is meaningful for compositional design of RT multiferroic materials based on four-layer structured Aurivillius compounds.
