摘要

摘要在平面异质结构中利用非线性磁电效应制造并研究了一种谐振电压倍频器，该异质结构包含置于两层非晶铁磁性 Metglas 合金之间的压电朗格酸盐单晶。频率倍增是由于 Metglas 磁致伸缩对磁场的非线性依赖。由于声品质因数高达 ~2820，在该结构的声共振频率下获得了 7.1 V/(cm Oe2) 的非线性磁电系数。在 2 Oe 的最佳偏置磁场和 0.8 kΩ 的匹配负载电阻条件下，倍增器的功率转换系数达到了 ~1%。

Frequency Doubler Based on Nonlinear Magnetoelectric Effect in a Planar Metglas/Langatate/Metglas Heterostructure

Abstract

A resonant voltage frequency doubler using the nonlinear magnetoelectric effect in planar heterostructure containing a piezoelectric langatate single crystal placed between two layers of amorphous ferromagnetic Metglas alloy was fabricated and studied. The frequency doubling occurred due to the nonlinear dependence of the Metglas magnetostriction on the magnetic field. A nonlinear magnetoelectric coefficient of 7.1 V/(cm Oe²) was obtained at acoustic resonance frequency of the structure due to high acoustic quality factor of ~2820. The power conversion coefficient of the doubler reached ~1% at optimal bias magnetic field of 2 Oe and matched load resistance of 0.8 kΩ.
