Abstract: 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—1.75)×105 V·m-1T-1 in the in-plane directions,but only 1.3×104 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.
