Abstract: Magnetoelectric (ME) effect has been studied in semicircular composites with a negative magnetostrictive/piezoelectric/positive magnetostrictiveNi/Pb(Zr,Ti)O3/FeCotrilayered structure. The ME behavior of theNi/Pb(Zr,Ti)O3/FeCois different from those in previous studies and zero-bias ME effects and four remarkable resonant peaks have been observed in the dependence of the ME voltage coefficient on the magnetic field frequency in the 1–150 kHz range. The effective excitation of the acoustical oscillations provided by the positive and negative magnetostrictive layers is responsible for the multifrequency ME effects. The results open up a suitable way to make multifunctional devices with multi-resonant-frequencies and/or zero-bias operations.
