我们报告了使用 Ni/[011]-Pb(Mg1/3Nb2/3)O3-Pb(Zr,Ti)O3 (PMN-PZT) 单晶/Ni 层压板实现了多重宽带磁电 (ME) 响应，该层压板利用了具有各向异性压电特性的层压板固有的多重机械共振。由于[011]取向PMN-PZT单晶的各向异性平面压电系数，层压板的ME电压系数显示出三种不同的谐振频率以及其符号和大小的大面内各向异性。在串联连接三个 Ni 层和 PMN-PZT 层之间具有不同厚度比的层压板后，我们观察到两个不同的频率窗口，带宽为 ∼60 kHz，显示出超过 16 V/cm Oe 的平坦、巨大的 ME 响应，这表明这些 ME 层压板是宽带场传感器或能量采集器应用的良好候选者。
We report the realization of a multiple, broadband, magnetoelectric (ME) response using Ni/[011]-Pb(Mg1/3Nb2/3)O3-Pb(Zr,Ti)O3 (PMN-PZT) single crystal/Ni laminates that take advantage of the multiple mechanical resonances inherent to laminates with anisotropic piezoelectric properties. The ME voltage coefficient of the laminates showed three distinct resonance frequencies and large in-plane anisotropy in its sign and magnitude owing to the anisotropic planar piezoelectric coefficient of [011]-oriented PMN-PZT single crystals. Upon serially connecting three such laminates with different thickness ratios between the Ni and PMN-PZT layers, we observed two distinct frequency windows with bandwidths of ∼60 kHz showing flat, giant ME responses of over 16 V/cm Oe, which suggests that these ME laminates are good candidates for application in broadband field sensors or energy harvesters.
