采用一种简单的热模压技术制备了由Terfenol - D/聚偏氟乙烯（PVDF）和锆钛酸铅（PZT）/PVDF颗粒复合层组成的多铁性层状复合材料。对极化方向和外加磁场方向之间不同测量角度以及在不同频率下的磁电系数进行了表征。结果表明，三相层状复合材料表现出显著的磁电效应，尤其是在出现机电共振的共振频率处。这种复合材料在约90 kHz时的最大磁电灵敏度约为6 V/cm·Oe。
Multiferroic laminated composites consisting of Terfenol-D/polyvinylidene-fluoride (PVDF) and lead-zirconate titanate (PZT)/PVDF particulate composite layers were prepared by a simple hot-molding technique. Magnetoelectric coefficients are characterized for the different measuring angles between the directions of polarization and applied magnetic field and at various frequencies. The results indicate that the three-phase laminated composites exhibit remarkable magnetoelectric effect especially at the resonance frequency at which the electromechanical resonance appears. The maximum magnetoelectric sensitivity of such composites is about 6 V/cm Oe at about 90 kHz.
