A giant current-to-voltage (I-V) gyration effect was found in magnetostrictive Tb1−xDyxFe2−y and piezoelectric Pb(Zr,Ti)O3 laminated composites. An equivalent circuit theory was developed for magnetoelectric gyration, which predicted that I-V conversion is reduced by a frequency transfer function ZR(f) and that the maximum occurs at resonance. A giant conversion coefficient up to 2500V∕A was predicted and confirmed.
