“…4(f). The higher polarization of the samples is attributed to the lower content of NFO, just because the NFO phase is paraelectric [18]. When BNTO content reaches to 0.8, the polarization of BNTO-NFO has a slow increase and after that, P max increases sharply with the increasing of BNTO.…”

Multiferroic ceramics xBi 0.5 Na 0.5 TiO 3 -(1-x-)NiFe 2 O 4 (x=0-1) have been prepared by a sol-gel method. Crystal structures were investigated by X-ray diffraction. The results show the samples are pure phases and increasing Bi 0.5 Na 0.5 TiO 3 content induces a gradual phase transformation from spinel to perovskite structure. Scanning electron microscopy micrographs also present the size and structure of the samples. Results from energy dispersive spectrometer confirm the stoichiometry of the compound. Both of the data are proved to agree with the results of X-ray diffraction. All of the samples display the evident ferromagnetic properties at 300 K and the saturation magnetization almost linearly varies with the increasing of x. The room temperature polarizationelectric field loops were examined. Compared with pure NiFe 2 O 4 , superior ferroelectric properties are obtained with increasing maximum of polarization as the content of Bi 0.5 Na 0.5 TiO 3 increases. Dielectric properties were also studied. The dielectric constant is proved to increase as Bi 0.5 Na 0.5 TiO 3 content increases at room temperature and the dielectric loss decreases as Bi 0.5 Na 0.5 TiO 3 doped in NiFe 2 O 4 . In addition, some of samples exhibit the effect of magnetoelectric coupling.

“…Composite sample with × = 0.07 has the highest dielectric constant at lower frequency, followed by × = 0.03 and 0.05. According to Liu et al (2013), due to inhomogeneity between the two phases in the composite which is between BaTiO 3 and MgFe 2 O 4 , there is a difference of the dielectric values at lower frequency (Liu et al 2013). The ferroelectric phase was spread among the spinel ferrite region in the composite.…”

“…Based on previous research, different compositions of perovkite BaTiO 3 and spinel ferrite powders altered the electrical and magnetic properties of the composite (Liu et al 2013;Ravindar Tadi et al 2010). In this study, MgFe 2 O 4 powders were synthesized via the sol-gel autocombustion method and then combined with commercial BaTiO 3 powders at 3 different weight fractions through a simple wet milling solid state reaction process to obtain BaTiO 3 -MgFe 2 O 4 composite materials with potential multiferroics properties.…”

“…Significant interest in the multiferroics composite research due to their multifunctionality leads to the combination between ferroelectric and piezoelectric material with the magnetic material. BaTiO 3 -CoFe 2 O 4 , NiFe 2 O 4 -BaTiO 3 and BaTiO 3 -Ni 0.7 Zn 0.3 Fe 2 O 4 are examples of some multiferroics composites with combination of ferrimagnetic and ferroelectric materials (Leonel et al 2011;Liu et al 2013;Zhang et al 2013). The ferrimagnetferroelectric characteristic can be used in multifunctional devices such as sensors, actuators and magnetoelectric transducers.…”

“…This effect allows controlling the polarization of a material using an external magnetic field and vice versa -a change of the magnetization with an electrical field. According to a phenomenological theory, the magnetoelectric response in a single-phased material is limited by dielectric constant and magnetic permeability [2]. Search of materials with high ferromagnetic and ferroelectric properties is actual task now.…”

We studied crystal and magnetic structures of some composite and single-phase multiferroics: (x)MFe 2 O 4 + (1-x)BaTiO 3 , Ni 3− Co V 2 O 8 , and Bi 0.9 Ba 0.1 Fe 0.9 Ti 0.1 O 3 . Composite multiferroics (x)MFe 2 O 4 + (1-x)BaTiO 3 with x = (0.2; 0.3; 0.4) and M = (Ni, Co) have ferrimagnetic structure, which is described by the propagation vector k = 0. Oxides Ni 3− Co V 2 O 8 with y = (0.1; 0.3; 0.5) possess a modulated magnetic structure, described by the vector k = ( , 0, 0), where = 0.283 and 0.348 at 7.4 K for y = 0.1 and 0.5, respectively. In the Bi 0.9 Ba 0.1 Fe 0.9 Ti 0.1 O 3 multiferroic a magnetic order is destroyed at 600 K and the Fe-ion magnetic moment decreases from = 3.46 (5) at 300 K to zero at 600 K.
