研究了镍锌铁氧体和锆钛酸铅多层膜的非线性磁电效应。在f= 1 mHz-1Hz的频率范围内，在高达1 kOe的交流磁场幅值H下测量了ME电压。对于跨多层产生的ME电压V观察到倍频，并且V的傅立叶分析示出f的谐波。随着H的增加或f的减小，由于磁致伸缩和样品电导率的非线性，V的形状被扭曲并且其幅度减小。
Nonlinear magnetoelectric (ME) effects have been investigated in a multilayer of nickel zinc ferrite and lead zirconate titanate. The ME voltage has been measured under ac magnetic field amplitudes H of up to 1kOe over the frequency range f=1mHz–1Hz. Frequency doubling is observed for the ME voltage V generated across the multilayer and Fourier analysis of V shows harmonics of f. As H is increased or f is decreased, the shape of V is distorted and its magnitude decreases due to nonlinearity of the magnetostriction and the sample conductivity.
