Abstract

Magnetoelectric (ME) effect has been studied in a simple composite structure made up of TbFe2 and Pb(Zr,Ti)O3. The working principal has also been analyzed. The ME coupling is achieved by end bonding instead of interface bonding. The influence of the bias magnetic field and the magnetic field frequency on ME coupling is discussed. The ME voltage coefficient depends strongly on the piezomagnetic coupling. The ME voltage coefficient and resonance frequencies for these composites are influenced by structural parameters. A large ME voltage coefficient as high as 14.1 V cm−1 Oe−1 is obtained. The large ME coefficient makes these structures possible for applications in sensors, actuators, and transducers.
