“…Multiferroic composites have drawn intensive interests in the past years due to the coexistence of ferroelectric and ferromagnetic ordering as well as the magnetoelectric coupling (ME) effect induced by both constituted phases [1][2][3][4]. Not only does the ME effect in these materials promise them a candidate for ME devices application [5], but these multiferroic materials could also be potentially used in devices which demand either ferroelectric or ferromagnetic properties, such as sensors, actuators and other devices which take advantage of ferroelectric and ferromagnetic properties simultaneously without their coupling properties [6][7][8].…”

“…Ba-and Sr-hexaferrites (Ba-and Sr-Fe 12 O 19 ) are well-known permanent magnet materials which have attracted extensive attentions due to their great technical importance [1]. The two type of materials have high magnetic anisotropy values, high Curie temperatures, relatively large values of total magnetization with excellent chemical stability and thus meet almost all requirement for permanent magnets.…”

“…Recently the development of methods of preparation magnetolelctric composite based with nanoscale of particle and crystallite size being done. There are other routes for the synthesis of magnetoelectric materials such as chemical solution deposition [11], sol-gel technique [12] and conventional solid-state sintering technique [13][14][15]. However, the high-energy ball milling (e.g.…”

“…Direct coupling between ferroelectric and ferromagnetic ordering in BFO, and ferroelectric and ferromagnetic coupling between BFO and PZT are found to be responsible for the magnetoelectric effect in the composite film. Chen et al (Chen et al 2010a) fabricated a thick film composite of CoFe 2 O 4 /PbZr 0.53 Ti 0.47 O 3 (CFO/PZT) assisted by polyvinyl pyrrolidone (PVP) employing a hybrid sol-gel processing and spin coating technique. They observed low value of magnetoelectric coupling coefficient due to the porous microstructure of the materials.…”

A different kind of multiferroics with ferroelectric-ferrimagnetic (FE-FM) composites: (1 -x) PbZr 0.53 Ti 0.47 O 3 -x Ni 0.65 Zn 0.35 Fe 2 O 4 with x = 0.10, 0.20 and 0.30, were synthesized by a powder-in-sol precursor hybrid processing route. Structural analysis with X-ray diffraction (XRD) data revealed the presence of both PbZr 0.53 Ti 0.47 O 3 (PZT) and Ni 0.65 Zn 0.35 Fe 2 O 4 (NZFO) pure phases in the PZT-NZFO composites. Scanning electron micrographs (SEM) clearly disclose distribution of both PZT and NZFO phases throughout the sample.Dielectric and electrical properties of the system have been investigated in a wide range of frequency at different temperatures. Dielectric constant (e r ) as a function of temperature reveals the paraelectric-FE transition temperature at *408°C having maximum value of e r at the peak [e r max = 1,200] with another low temperature anomaly at *297°C, very close to the magnetic Curie temperature of the NZFO ferrite (T c = 300°C) for the x = 0.1 FE-FM composite. The impedance spectroscopy data of these composites show clearly, contribution of both grain and grain boundary effect in the electrical properties of the composites. Negative temperature coefficient of resistance (NTCR) behavior of the materials indicates their semiconducting nature. The ac conductivity spectrum is found to obey Johnscher's power law very well. The temperaturedependent magnetization hysteresis (M-H) loops of the PZT/NZFO composite show excellent non-saturating ferrimagnetic behavior with increase in both coercive field (H c ) and remanent magnetization (M r ) when the NZFO content in the composite is increased. Polarization (P) versus electric field (E) studies at 300 K give conclusive evidence of the presence of spontaneous polarization in all the three composites (x = 0.1, 0.2 and 0.3). However, area of P-E loop, coercive field (E c ) and remanent polarization (P r ) are found to decrease noticeably with the increase of the NZFO content (x) in these composites.
