Аннотация

Multiferroic laminated composites consisting of Terfenol-$D$/polyvinylidene-fluoride (PVDF) and lead-zirconate titanate (PZT)/PVDF particulate composite layers were prepared by a simple hot-molding technique. Magnetoelectric coefficients are characterized for the different measuring angles between the directions of polarization and applied magnetic field and at various frequencies. The results indicate that the three-phase laminated composites exhibit remarkable magnetoelectric effect especially at the resonance frequency at which the electromechanical resonance appears. The maximum magnetoelectric sensitivity of such composites is about $6\phantom{\rule{0.3em}{0ex}}\mathrm{V}∕\mathrm{cm}\phantom{\rule{0.2em}{0ex}}\mathrm{Oe}$ at about $90\phantom{\rule{0.3em}{0ex}}\mathrm{kHz}$.
