Abstract The influence of constant electric field on the characteristics of the direct magnetoelectric effect in composite structures with single crystal piezoelectric layers was observed. The effect was measured in the structures with langatate and catangasite piezoelectric layers and amorphous magnetic alloy metglas as a ferromagnetic layer. The value of magnetoelectric voltage coefficient of 146 V/(Oe·cm) was obtained for the langatate-based structure and value of 1.35 V/(Oe·cm) for the catangasite-based structure. For the langatate-metglas structure, electrical field of 20 kV/cm resulted in a change in the generated voltage up to 63%, in the quality factor Q up to 76%, and provided linear variation of the resonance frequency up to 16 Hz. Electrical field control of magnetoelectric effect characteristics can be used to design new magnetoelectric devices.

摘要 研究了恒定电场对单晶压电层复合结构直接磁电效应特性的影响。该效应是在具有 langatate 和 catangasite 压电层以及作为铁磁层的非晶磁性合金金属玻璃的结构中测量的。得到了146 V/(Oe·cm)的磁电电压系数值对于基于langatate的结构和1.35 V/(Oe·cm)的基于钙钛矿的结构的值。对于 langatate-metglas 结构，20 kV/cm 的电场导致产生的电压变化高达 63%，品质因数 Q 高达 76%，并提供高达 16 Hz 的谐振频率的线性变化。
