Abstract :
Five magnetoelectric laminates of polymer-bonded Terfenol-D magnetostrictive composite (i.e., volume fractions (Vp) ranging from 0.16 to 0.48) and lead zirconate titanate (PZT-5H) piezoelectric ceramic were fabricated. The measured quasistatic magnetoelectric voltage coefficient (αE) increased gradually with increasing Vp and approached saturation for Vp>0.4 due to increased elastic modulus and piezomagnetic coefficient of the magnetostrictive phase. A maximum αE of 2.7 V/cm·Oe was observed at a magnetic bias field (HBias) of 53 kA/m for the laminate with Vp=0.48. αE was found to be a fairly linear function of HBias at 100-220 kA/m bias for all Vp values. dαE/dHBias as a function of HBias was found to increase with increasing Vp for HBias values of 100-220 kA/m.
