Fe BSi C 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)O_3/metglas was fabricated. Without any external magnetic field, the composite exhibits the ME coefficient ~aE31 of 103 m V/(cm Oe) at1 k Hz 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 10-7T at 1 k Hz. It is expected that such self-biased ME composites provide a practical application of economical and compact magnetic sensors.
