Barium titanate is still the prototype of a piezoelectric crystalline material that has attracted many researchers and industrial partners to use. A modified citrate method was used to create barium titanate nanoparticles BaTi1−xZrxO3. The samples were crystallized in a single-phase tetragonal structure, as revealed using X-ray powder diffraction. The crystallite size decreases with increasing Zr concentration. Fourier-transform infrared spectra showed the main absorption bands of the samples BaTi1−xZrxO3. Field emission scanning electron microscopy micrographs illustrate that the doped sample BaTi0.9Zr0.1O3 is more porous and finer than the parent. For low Zr doping concentrations (x = 0.1), the ferroelectric properties of barium titanate are improved. The conduction mechanisms in the samples are small polaron hopping and correlated barrier hopping. The Zr/Ti ratio is a crucial parameter for tailoring the ferroelectric–paraelectric phase transition.

“…It is known that, by adjusting the fabrication conditions, the content, and types of doping, the structure and the physical properties of BTO can be tuned [37][38][39]. Additionally, BTO is also a lead-free ferroelectric material with wide bandgap and quite high Curie temperature [40][41][42][43][44][45]. Therefore, BTO was chosen as a typical FE material to create multiferroic composites, such as BaTiO 3 -NiFe 2 O 4 [26], BaTiO 3 -CoFe 2 O 4 [41], BaTiO 3 -Ni 0.7 Zn 0.3 Fe 2 O 4 [46], Ba 0.9 Sr 0.1 Ti 0.9 Zr 0.1 O 3 -CoFe 2 O 4 [47], Ba 0.85 Ca 0.15 Ti 0.9 Zr 0.1 O 3 -CoFe 2 O 4 [48], BaTiO 3 -CoFe 2 O 4 [49], BaTiO 3 -BiFeO 3 [50], BaTiO 3 -Bi 0.85 La 0.15 FeO 3 [51], [0.5(Ba 0.7 Ca 0.3 TiO 3 )−0.5(BaZr 0.2 Ti 0.8 O 3 )]-Co 0.9 NiFe 2 O 4 [52].…”

Multiferroic nanocomposites of xNiFe2O4/(1-x)BaTiO3 (x = 0, 0.1, 0.2, 0.3, and 0.4) (denoted as NFO-BTO) with the particle size about of 70 nm were prepared by the high energy mechanical milling combined with the thermal annealing methods. The X-ray diffraction patterns show a presence of NiFe2O4 (NFO) and BaTiO3 (BTO) phases. The values of the characteristic parameters of nanocomposites such as the coercive field (E c), the residual polarization (P r), the remanent magnetization (M r), the saturation magnetization (M s), and the coercive force (H c) increase gradually with an increase in NFO concentration. For an applied electric field below 10 kV/cm, the values P r and E c are found to be 0.004-0.038 µC/cm2 and 0.7-2.0 kV/cm, corresponding x = 0.1-0.4, respectively. Changes in electrical and magnetic properties of composites depend heavily on the NFO content, which will be studied specifically. Additionally, the ability to absorb microwave at room temperature of a representative sample with x = 0.3 mixed in acrylic paint (denoted as NFO-BTO-AP) in a frequency range of f = 12-18 GHz has also been investigated. It shows a large negative reflection loss (RL) with RL = -39.8 dB occurring at around 16.8 GHz corresponding to the absorptivity of over 99.9% for an absorbing layer with thickness of 5.5 mm. This suggests that NFO-BTO nanocomposites could be considered as a potential material in the field of absorbing and shielding electromagnetic waves.
