A new composite system, Ba(Zr0.07Ti0.93)O3 (BZT93) ceramic/NiO nanoparticles, was fabricated to investigate the effect of NiO nanoparticles on the properties of these composites. M-H hysteresis loops showed an improvement in the magnetic behavior for higher NiO content samples plus modified ferroelectric properties. However, the 1 vol.% samples showed the optimum ferroelectric and ferromagnetic properties. Examination of the dielectric spectra showed that the NiO additive promoted a diffuse phase transition, and the two phase transition temperatures, as observed for BZT93, merged into a single phase transition temperature for the composite samples.
制备了一种新型复合体系Ba(Zr0.07Ti0.93)O3（BZT93）陶瓷/NiO纳米颗粒，以研究NiO纳米颗粒对这些复合材料性能的影响。M-H磁滞回线表明，较高NiO含量的样品的磁性能有所改善，同时铁电性能也得到了改善。然而，1 vol.%的样品表现出最佳的铁电和铁磁性能。介电谱研究表明，NiO添加剂促进了漫散相变，并且如BZT93所观察到的两个相变温度合并为复合样品的单一相变温度。
