N2 - Magnetoelectric (ME) coupling in multiferroic composites of Fe 70Pd30/lead zirconate titanate (PZT)/Fe 70Pd30 trilayers was investigated. An Fe 70Pd30 ribbon and Fe70Pd30 films were prepared by rapid solidification and sputtering techniques, respectively. The saturated value of magnetostriction of the ribbon 30 ×m in thickness was 95 ppm at a steady magnetic field of 200 Oe. Those of the films were 22 to 67 ppm depending on the film thickness. The output ME voltage VME of the trilayer composites, which was measured at a driving ac magnetic field Hac at 1 Hz, increased with increasing magnetostriction. The V ME of the ribbon/PZT/ribbon composite exhibited a very large peak at a resonant frequency of 64 kHz and responded to an Hac of 0.0025 Oe. However, for the film/PZT/film composite, VME linearly increased with increasing Hac in a wide frequency range of 1 to 104 Hz.
