Ceramic composites based on Pb(Zr,Ti)O3/NiFe2O4 (PZT–NFO) have been synthesized from the conventional solid-state reaction method. The ferroelectric and magnetic properties have been investigated at room temperature. The obtained results revealed excellent characteristics of both ferroic responses, which suggest the studied ceramic composite as a promising material for practical applications in magneto-electric related devices.

The conductive processes in multiferroic ceramic composites based on PbZr0.65Ti0.35O3 (PZT) and BaFe12O19 (BaM), synthesized by the conventional solid-state reaction method, have been investigated. The DC and AC electrical conductivities have been analyzed in a wide temperature and frequency range and the influence of the BaM content on the electrical properties of the PZT- xBaM composites has been taken into account. It has been observed that the inclusion of the BaM in the PZT ferroelectric matrix promotes conduction mechanisms with magnetic-order characteristics on the ceramics, which were related to doubly ionized oxygen vacancies, superexchange, and double-exchange-type interactions. The obtained results are discussed in the framework of Jonscher's formalism. [ABSTRACT FROM AUTHOR]

The ferroelectric, magnetic, and magneto-electric properties of a PZT/Ba-hexaferrite (PbZr0.65Ti0.35O3/BaFe12O19) ceramic composite are reported. The expected rhombohedral-PZT and Ba-hexaferrite phases have been confirmed from structural and Rietveld refinement analyses, without additional undesired phases. Well-saturated ferroelectric and magnetic hysteresis loops confirmed the ferroelectric and magnetic nature of the study system, revealing enhanced characteristics when compared to those reported for typical multiferroics. The existence and enhancement of the magneto-electric response have been demonstrated by measuring the effect of the external DC magnetic field on the dielectric permittivity. The obtained results suggest an excellent candidate for room temperature multiferroic system with enhanced properties. [ABSTRACT FROM AUTHOR]
