摘要：

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. (C) 2017 Elsevier B.V. All rights reserved.
