Abstract
The magnetoelectric (ME) effect in double-layer composite disk resonators containing mechanically joined layers of magnetostrictive nickel and piezoelectric lead zirconate titanate is experimentally studied. A resonant growth of the efficiency of the ME interaction is discovered at the frequencies of the flexural and radial modes of mechanic vibrations of the resonator. Frequencies of the flexural and radial vibrations of double-layer ME resonators are calculated. The possibilities of controlling the efficiency of the ME interaction by means of selecting the thicknesses of the structure layers and the orientation of the external permanent magnetic field are demonstrated. The sensitivity of the sensors of low-frequency magnetic fields based on ME resonators is estimated.
