In this paper, we report the nonlinear magnetoelectric response in a homogenous magnetostrictive/piezoelectric laminate material. The proposed magnetoelectric stack FeCuNbSiB/piezofiber is made up of high-permeability magnetostrictive FeCuNbSiB foils and a piezoelectric Pb(Zr, Ti)O fiber composite. The time dependence of magnetoelectric interactions in the FeCuNbSiB/piezofiber structure driven by pulsed magnetic field was investigated in detail. The experimental results show that the magnetoelectric effect is strongly dependent on the external bias magnetic and pulsed magnetic field parameters. To detect the amplitude of a pulsed magnetic field, the output sensitivity reaches 17 mV/Oe, which is excited by a 100 μs width field. In addition, to measure the pulsed width, the output sensitivity reaches 5.4 mV/μs in the range of 0-300 μs. The results show that the proposed FeCuNbSiB/piezofiber sensor is ideally suited for pulsed magnetic field measurement.
在本文中,我们报道了一种均匀磁致伸缩/压电层状材料中的非线性磁电响应。所提出的磁电堆栈FeCuNbSiB/压电纤维由高磁导率磁致伸缩FeCuNbSiB箔片和压电Pb(Zr,Ti)O纤维复合材料组成。详细研究了由脉冲磁场驱动的FeCuNbSiB/压电纤维结构中磁电相互作用的时间依赖性。实验结果表明,磁电效应强烈依赖于外部偏置磁场和脉冲磁场参数。为了检测脉冲磁场的幅度,由宽度为100μs的场激发时,输出灵敏度达到17mV/Oe。此外,为了测量脉冲宽度,在0 - 300μs范围内输出灵敏度达到5.4mV/μs。结果表明,所提出的FeCuNbSiB/压电纤维传感器非常适合于脉冲磁场测量。
