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 Vpand approached saturation for Vp> 0.4 due to increased elastic modulus and piezomagnetic coefficient of the magnetostrictive phase. A maximum αEof 2.7 V/cm · Oe was observed at a magnetic bias field (HBias) of 53 kA/m for the laminate with Vp= 0.48. αEwas found to be a fairly linear function of HBiasat 100-220 kA/m bias for all Vpvalues. dαE/dHB iasas a function of HB iaswas found to increase with increasing Vpfor HB iasvalues of 100-220 kA/m.
