摘要：

Magnetoelectric (ME) coupling in multiferroic composites of Fe70Pd30/lead zirconate titanate (PZT)/Fe70Pd30 trilayers was investigated. An Fe70Pd30 ribbon and Fe70Pd30 films were prepared by rapid solidification and sputtering techniques, respectively. The saturated value of magnetostriction of the ribbon 30 mu 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 V-ME of the trilayer composites, which was measured at a driving ac magnetic field H-ac 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 H-ac of 0.0025 Oe. However, for the film/PZT/film composite, V-ME linearly increased with increasing H-ac in a wide frequency range of 1 to 104 Hz. (C) 2011 The Japan Society of Applied Physics
