Self-biased magnetoelectric effect in（Pb, Zr）TiO3/metglas laminates by annealing method

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）O3/metglas was fabricated. Without any external magne...

Summary: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）O3/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.
