The paper describes the experimental results of magnetoelectric (ME) effect in the area of magnetoacoustic resonance (MAR) in ferrite-piezoelectric bilayer. In the materials ME effect is appeared as a result of interaction of magnetostrictive and piezoelectric components. The aim of the work consisted in the experimental investigation of ME effect in the MAR area of ferrite. Bilayer ME element was made from piezoelectric lanthangallium silicate (LGS) and yttrium-iron garnet (YIG). The paper presents the experimental data of direct ME effect for the sample of YIG-LGS in the MAR area. The magnitude of ME effect amounted to 14.1 V/(cm·Oe) at frequency about 2.8 MHz. The measurements were carried out by two methods that had comparable results. The obtained data allow to state that the realization of radio and microwave devices using ME effect in the MAR area is possible.
