制备了具有负磁致伸缩层/压电层/正磁致伸缩层的Ni-PZT-TbFe 2三层磁电薄膜。讨论了偏置磁场和磁场频率对电磁耦合的影响。Ni-PZT-TbFe_2三层膜的ME系数行为与Ni-PZT-Ni和TbFe_2-PZT-TbFe_2三层膜的ME系数行为不同。两个显着的共振峰已被观察到的ME电压系数的磁场频率的依赖关系，这使得这些Ni-PZT-TbFe 2三层适用于多功能器件的多频操作。
A magnetoelectric (ME) Ni–PZT–TbFe2trilayer with negative magnetostrictive/piezoelectric/positive magnetostrictive layers has been prepared. The influence of the bias magnetic field and the magnetic field frequency on ME coupling is discussed. The ME coefficient behavior of the Ni–PZT–TbFe2trilayer is different from that of Ni–PZT–Ni and TbFe2–PZT–TbFe2trilayers. Two remarkable resonance peaks have been observed in the dependence of the ME voltage coefficient on the magnetic field frequency, which makes these Ni–PZT–TbFe2trilayers suitable for applications in multifunctional devices with multifrequency operation.
