Multiferroicity in 0.7Pb(Zr 0.52 Ti 0.48 )O 3 -0.3Pb(Ni 1/3 Nb 2/3 )O 3 ceramics

0.7Pb(Zr 0.52 Ti 0.48 )O 3 -0.3Pb(Ni 1/3 Nb 2/3 )O 3 (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 ( T m ), indicates a lead-induced ferroelectric behavior.
