Magnetoelectric effect of Pb(Zr,Ti)O3 rod arrays in a (Tb,Dy)Fe2/epoxy medium -: art. no. 012503

We report a kind of multiferroic and multifunctional composite with Pb(Zr,Ti)O-3 rod arrays embedded in a ferromagnetic medium of (Tb,Dy)Fe-2/epoxy. The composite structure is similar to that of 1-3-type piezoelectric composites with Pb(Zr,Ti)O-3 rod arrays embedded in an inert epoxy for already commercial applications as transducers. The large magnetoelectric effect, especially at high frequency at which the electromechanical resonance appears, is observed for such multiferroic composites due to coupling elastic interaction between Pb(Zr,Ti)O-3 rods and the ferromagnetic medium, which suggests avenues for designing novel multiferroic materials for practical applications.
