Self-amplified magnetoelectric properties in a dumbbell-shaped magnetostrictive/piezoelectric composite

IEEE Trans Ultrason Ferroelectr Freq Control. 2012 May;59(5):859-62. doi: 10.1109/TUFFC.2012.2270.

Abstract

We report magnetoelectric (ME) properties in a dumbbell-shaped metallic glass alloy/Pb(Zr(x)Ti(1-x))O(3) laminated composite, yielding a magnetic field amplification resulting from magnetic flux concentration effects of the dumbbell-shaped design. Compared with the traditional rectangular structures, the modified geometry results in an effective improvement in the ME coefficient, a significant decrease in the required dc magnetic bias field, and an enhancement in magnetic field sensitivity.
