Abstract

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