Abstract

FeBSiC metglas was annealed at an optimized condition (350 °C, 5 min) to achieve the mixed phases with pristine amorphous phase and crystallization phase. With such annealed metglas, a self-biased magnetoelectric (ME) laminate of metglas/Pb(Zr, Ti)O3/metglas was fabricated. Without any external magnetic field, the composite exhibits the ME coefficient αE31 of 103 mV/(cm Oe) at 1 kHz and 15.5 V/(cm Oe) at electromechanical resonance frequency. The induced ME voltage shows a good linear relation to the applied AC magnetic field with amplitude as low as 10−7 T at 1 kHz. It is expected that such self-biased ME composites provide a practical application of economical and compact magnetic sensors.
