“…The XRD patterns of CAF and BCZT composites with different ratios of both components are shown in figure 2. The spinel cubic structure of CAF and the orthorhombic structure with Pbnm space group for BCZT was identified by XRD [19]. The minor Fe 2 O 3 impurity phase was found in the XRD pattern.…”

Multiferroics with strong magnetoelectric coupling can be created by improving the magnetostriction of the ferrite phase and combining it with the best known piezoelectric. Herein, the ferromagnetic CoFe2O4 was modified with Al3+ ions (CAF) to further improve the resistivity, magnetic, and magnetostrictive properties and then combined with (0.5)Ba(Zr0.2Ti0.8)O3−(0.5)(Ba0.7Ca0.3)TiO3(BCZT) with different weight percentages. XRD results revealed the presence of a mixed spinel cubic phase for CAF (Fd-3m), whereas BCZT crystallized in a tetragonal structure (Amm2) in composite systems. Composites exhibited well-developed hysteresis loops with no feature of leakage current and dielectric response was consistent with ferroelectric properties. The magnetic response of CAF sample improved significantly which is attributed to preference of Al3+ ions on tetrahedral sites. The magnetization of composites increased as the nonmagnetic BCZT component increased and (0.75)CAF-(0.25)BCZT system had the highest saturation magnetization. We anticipate that these systems will have significantly improved magnetoelectric characteristics than unmodified CF-BCZT system.

“…Naveed-Ul-Haq [20] studied the dielectric properties of 85 wt.% [0.5Ba(Zr0.2Ti0.8)O3 − 0.5(Ba0.7Ca0.3)TiO3] − 15 wt.% [CoFe2O4] composite ceramics obtained from piezoelectric and ferrite powders synthesized by the solid state method. Mixed and layered [xCoFe2O4 (CFO) − (1 − x)(Ba0.85Ca0.15) (Zr0.1Ti0.9)O3 (BCZT)] composites were described in articles [21,22]. The original auto-combustion technique was used to synthesize CFO nanoparticles, which were added to the BCZT precursor gel, then the composite powders were calcined at 800 °C and sintered at 1300 °C to obtain particulate composites.…”

Magnetoelectric lead-free composite ceramic based on the piezoelecrtic Ba0.85Ca0.15Ti0.9Zr0.1O3 (BCZT) and magnetic NiCo0.02Cu0.02Mn0.1Fe1.8O4‑d (NCCMF) has been obtained by the solid state method using preliminarily synthesized by the solid-state method precursors. X-ray diffraction measurements, microstructural, magnetic, dielectric, piezoelectric and magnetoelectric studies have been carried out. Impurity phases were not contained in the composites, and there were no signs of interfacial interaction even at the doping level. Ceramics has a high electrical resistivity at direct current (~109 Ω·cm) and, over the entire range of x studied, exhibits a combination of magnetic and piezoelectric parameters, which vary over a wide range and clearly depend on the composites composition. The maximum magnetoelectric coupling coefficient ΔE/ΔH ≈ 90 mV/(cm·Oe) at a frequency of 1 kHz has been observed for specimens with x = 60–70%.
