Abstract :
We report magnetoelectric (ME) properties in a dumbbell-shaped metallic glass alloy/Pb(ZrxTi1-x)O3 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.
