The resonant enhancement of the magnetoelectric coupling effect due to the bending and length modes had been investigated in the asymmetrical bilayered heterostructure consisting of the La_0.7Sr_0.3MnO₃ and BaTiO₃ deposited on SrTiO₃.The frequency-dependent transverse magnetoelectric voltage coefficient demonstrated two sharp peaks in the vicinity of electromechanical resonant frequencies, which were attributed to the bending and length vibration modes, respectively. The value of the magnetoelectric voltage coefficients for the first peak was higher than that of the second one, which ascribed to the phase shift between the excited magnetic field and induced dielectric polarization. This result demonstrated the asymmetrical bilayered heterostructure has dramatically enhanced magnetoelectric effect when operated near these frequencies, which is likely to provide a tremendous opportunity for configuring the corresponding devices.

在由沉积在 SrTiO ₃上的 La _0.7 Sr _0.3 MnO ₃和 BaTiO ₃组成的不对称双层异质结构中研究了由于弯曲和长度模式引起的磁电耦合效应的共振增强.与频率相关的横向磁电电压系数在机电共振频率附近表现出两个尖峰，分别归因于弯曲和长度振动模式。第一个峰的磁电电压系数值高于第二个峰，这归因于激发磁场和感应电介质极化之间的相移。这一结果表明，当在这些频率附近工作时，非对称双层异质结构显着增强了磁电效应，这可能为配置相应的器件提供了巨大的机会。
