Complex impedance and magnetoelectric effect analyses of a novel three-ply-structured (Tb0.3Dy0.7)0.75Pr0.25Fe1.55-Pb(Zr0.53Ti0.47)O3 nanoceramic composites

► ME nanoceramic composites combining the nano-sized metal and ferroelectric powders. ► Ferromagnetism remained despite the new structure composites sintered at 900 °C in air. ► High DC resistivity was observed nearly independent of the metal content. ► Insignificant eddy-current losses were observed between 10 Hz and 200 kHz at RT. ► A stable ME effect was found in 1-150 kHz except for the resonance around 111 kHz.
