中文摘要：
用带底座的Pb（Zr，Ti）O3薄片阵列作为压电相，Terfenol-D粉末与树脂的混合物作为磁致伸缩相，灌注复合得到准2—2型磁电多层三相复合材料．研究了这种准2-2型多层结构在不同偏置磁场和不同角度下的磁电效应．其面内相互垂直的两个方向磁电电压系数分别在0．15和0．225T磁场下达到峰值，低频下分别为1．62×10^5V·m^-1T^-1和1．75×10^5V·m^-1T^-1；而在垂直于面内方向，低频下磁电系数仅有1．3×10^4V·m^-1T^-1，体现出显著的磁电各向异性．这种准2．2型磁电多层复合材料具有较好的交流磁场灵敏度，在谐振频率下可以探测到10^-9T的交流磁场的变化．进行合适的设计和排列，可以探测空间磁场的大小和方向，有望应用于磁场传感器等领域．
英文摘要：
A pseudo 2-2 type multilayered magnetoelectric composite of Pb（Zr, Ti）O3 slice array （with base） and Terfenol-D/epoxy medium was prepared by the dice-and-fill technique. Obvious magnetoelectric anisotropy was observed in the pseudo 2-2 type composite, e. g., the magnetoelectric coefficients at low frequency were about （ 1.62×10^5V·m^-1T^-1 in the in-plane directions, but only 1.3× 10^4 V·m^-1T- 1 in the out-of-plane direction. The pseudo 2-2 type composite can detect AC magnetic field as small as 10-9 T under resonance drive. The magnetoelectric anisotropy and high magnetic field sensitivity make such pseudo 2-2 type multilayered magnetoelectric composites detect both direction and magnitude of magnetic field, which is of technological importance for applications as magnetic sensors.
