摘要

Magnetoelectric response at the radio frequency range has been studied as a function of temperature. For that purpose, we have fabricated sandwich-type laminated composites in which the FeCoSiB alloy was used as the magnetostrictive element and polyvinylidene fluoride (PVDF) as the piezoelectric one. The FeCoSiB amorphous ribbon shows good magnetic properties, with a magnetostriction close to 30 ppm and a piezomagnetic coefficient in as-quenched state and for a long ribbon of ppm/Am. Even though PVDF shows a higher piezoelectric coefficient ( pC/N) than the high temperature poly and copolymides, the advantage of using these poly- and copolymides is the great stability shown at temperatures close to 200 °C. Considering this, the influence of temperature in laminated composites and in their components (epoxy, piezoelectric, and magnetostrictive constituents) has been measured and discussed.
