研究了0.50BaTiO（3）-0.50Ni（0.5）Zn（0.5）Fe（2）O（4）磁电复合材料的磁性能与微结构的关系。通过两种方法制备了双相陶瓷：（i）将BaTiO 3和Ni 0.5Zn 0.5Fe 2 O 4粉末混合;（ii）在含有BaTiO 3粉末的溶液中通过共沉淀Fe、Ni和Zn盐。通过第二种方法获得了均匀的微观结构，更高的密度和更好的两相混合，从而产生更高的磁矩。这种复合材料的磁性能由铁氧体的浓度和性能以及两相的连接程度决定。(c)2007 Elsevier B. V.保留所有权利。
The magnetic properties related to the microstructures in the 0.50BaTiO(3)-0.50Ni(0.5)Zn(0.5)Fe(2)O(4) magneto-electric composites are investigated. The di-phase ceramics were prepared by two methods: (i) mixing powders of BaTiO3 and Ni0.5Zn0.5Fe2O4 and (ii) by co-precipitation of Fe, Ni and Zn salts in solutions containing BaTiO3 powders. Homogeneous microstructures, higher density and better mixing of the two phases were obtained by the second method, giving rise to higher magnetic moments. The magnetic properties in such composites result as determined both by the ferrite concentration and properties and by the degree of connectivity of the two phases. (c) 2007 Elsevier B.V.
