Abstract
The article presents an experimental study of the magnetoelectric (ME) effect in composite structures with closed geometry in the form of a toroid. The experimental study was carried out on the basis of magnetostrictive-piezoelectric Metglas (AMAG-225) and PZT-19 materials. It has been found that the value of the output voltage increases due to an increase in the volume fraction of the magnetostrictive phase to a certain number of layers. The experimentally obtained dependences of the output voltage on the frequency of the supplied signal at constant current values are presented. It is also shown that with an increase in the number of Metglas layers in the structure, a shift in the resonant frequency is observed. The main advantage of this structure is the uniform distribution of the magnetic flux and the independence of this distribution from the position of the direct current wire within the hole. The magnetostrictive-piezoelectric structure investigated in the article provides ample opportunities for designing various magnetoelectronic systems, for example, contactless high current sensors with wireless data transmission.
