Multiferroicity in 0.7Pb(Zr0.52Ti0.48)O3-0.3Pb(Ni1/3Nb2/3)O3 ceramics

0.7Pb(Zr0.52Ti0.48)O3-0.3Pb(Ni1/3Nb2/3)O3 (abbreviated as PZT-PNN) ceramics were prepared using the solid-state reaction method. The results reveal that ferroelectric and anti-ferromagnetic orderings coexist (multiferroicity) in PZT-PNN ceramics. Furthermore, the abnormal behavior of dielectric constant and loss observed at Néel temperature gives an evidence of the coupling between the ferroelectric and anti-ferromagnetic orderings (magnetoelectric coupling). The ferroelectric loops become slimmer with increasing temperature and the remnant polarization persists up to above the temperature of dielectric maximum (Tm), indicates a lead-induced ferroelectric behavior.
