“…These properties play an important role in the fabrication of components such as a transformer core, antenna rods, multi-layer chip inductor, micro-inductors, electromagnetic filters, etc. [1][2][3][4] Recently, researchers synthesized ferrites in the form of nanoscale range because of its growing applications such as production of bio-diesel [5], nano-catalyst [6], humidity sensor [7], gas sensor [8], super-capacitor [9], electrode material for Li-ion battery [10], etc. Various methods such as sol-gel auto-combustion, co-precipitation, citrate precursor, wet chemical route, hydrothermal [11][12][13][14][15], etc.…”

The ferrite material with compositions Ni 0.7 Cu 0.1 Zn 0.2 La x Fe 2−x O 4 (where x = 0, 0.015, 0.025, and 0.035) was synthesized by oxalate co-precipitation method. The ferrite samples were characterized by thermo-gravimetric and differential temperature analysis (TG-DTA), energy-dispersive X-ray analysis (EDAX), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), field-emission scanning electron microscopy (FE-SEM), and vibrating sample magnetometer (VSM) techniques. The EDAX analysis confirmed the formation of required stoichiometric ferrite samples. The formation of cubic spinel structure with the presence of weak ortho-ferrite phases was confirmed from X-ray diffraction analysis. The lattice constant of all the ferrites was found to be increase with increase in La 3+ content. The presence of main two recognized strong absorption bands in the frequency range 400-600 cm −1 in the FTIR spectra shows the formation of well spinel ferrite. Morphological study shows that grain size of the ferrites lies in the range 16.23-24.21 nm. It is observed that the saturation magnetization and magnetic moment of Ni-Cu-Zn ferrites decrease with La 3+ content.

“…Fortunately, this limitation of ME effect in single phase multiferroics is absent in composite multiferroics. By combining a ferroelectric phase with ferromagnetic, composite multiferroic material has strong magnetoelectric coupling effect at room temperature [16][17][18][19][20][21]. The magnetoelectric coupling effect of composite is considered to be the piezoelectric effect of the ferroelectric phase and the magnetostrictive effect of the ferromagnetic phase.…”

Magnetoelectric composites have attracted much attentions due to their excellent multiferroic properties at room temperature. In this paper, CoFe 2 O 4 -PbZr 0.52 Ti 0.48 O 3 (CFO-PZT) composite ceramics with different molar ratios (CFO/PZT=1:4, 1:5, 1:6 and 1:7) were prepared by conventional solid reaction method. Effects of molar ratio on the structure, dielectric, ferroelectric and magnetic properties were comparatively investigated. X-ray diffraction patterns confirmed biphase structures of the composites, which can be indexed as CFO and PZT, no other obvious phase can be found with the limitation of the XRD resolution. Scanning electron microscopy (SEM) images show that the surface of the prepared samples is not dense enough and many pores are formed, the mean grain size is about 200 nm. The same relaxation behavior was observed in the intermediate temperature range of PZT-CFO composite ceramics. At room temperature, the dielectric constant and dielectric loss of the specimen 1:4 are the highest. The leakage current of the sample 1:4 is the lowest while the sample 1:6 has the largest value. As the CFO content in the composite decreases, both the saturation (Ms) and the remnant (Mr) magnetization decrease. Among them, the sample 1:4 presents better ferroelectric and magnetic properties, the remnant polarization is 1.13 μC cm −2 , the saturation magnetization and remnant magnetization are 11.01 and 3.28 emu g −1 , respectively. The sample 1:6 has the largest coercive field (945.27 Oe) while the sample 1:7 show the smallest value (681.19 Oe). Interface interaction between CFO/PZT may be applied to explain this phenomenon.
