【 摘 要 】

The colossal magnetodielectric effect is reported in Pb(Zr,Ti)O₃/Terfenol-D laminate composite under low magnetic field. When the composite is placed in an external a.c. magnetic field, magnetoelectric effect is produced, as a result, the dielectric properties of the Pb(Zr,Ti)O₃ is changed, i.e. magnetodielectric effect. Both the amplitude and resonance frequency change with the external magnetic field. The colossal magnetodielectric coefficient of 5 Ã�? 10⁴%at low magnetic field of 20 Oe is achieved near the electromechanical resonance frequency.
