Magnetoelectric (ME) composites that simultaneously exhibit ferroelectricity and ferromagnetism have recently gained significant attention as evident by the increasing number of publications. These research activities are direct results of the fact that multiferroic magnetoelectrics offer significant technological promise for multiple devices. Appropriate choice of phases with co-firing capability, magnetostriction and piezoelectric coefficient, such as Ni-PZT and NZFO-PZT, has resulted in fabrication of prototype components that promise transition. In this manuscript, we report the properties of Ni-PZT and NZFO-PZT composites in terms of ME voltage coefficients as a function of frequency and magnetic DC bias. In order to overcome the problem of toxicity of lead, we have conducted experiments with Pb-free piezoelectric compositions. Results are presented on the magnetoelectric performance of Ni-NKN, Ni-NBTBT and NZFO-NKN, NZFO-NBTBT systems illustrating their importance as an environmentally friendly alternative.
同时表现出铁电性和铁磁性的磁电（ME）复合材料最近受到了广泛关注，这从越来越多的出版物中可见一斑。这些研究活动是多铁性磁电材料为多种器件带来重大技术前景这一事实的直接结果。选择具有共烧能力、磁致伸缩和压电系数的合适相，如Ni-PZT和NZFO-PZT，已导致制造出有望实现转变的原型组件。在本手稿中，我们报告了Ni-PZT和NZFO-PZT复合材料的磁电电压系数随频率和直流磁偏置的变化特性。为了克服铅的毒性问题，我们使用无铅压电组合物进行了实验。展示了Ni-NKN、Ni-NBTBT和NZFO-NKN、NZFO-NBTBT系统的磁电性能结果，说明了它们作为环保替代品的重要性。
