“…The crystallographic structure of the mullite is represented by a central symmetric [74], orthorhombic structure [73] with two atoms of Bi +2 , four atoms of Fe +2 , and 9 atoms of oxygen [75] with different valency. The lattice parameters are a=b=8 Å [1], c=6 Å [74] and the cell value is around 400-410 Å [74,76]. The parameters may differentiate due to structure defects during the preparation process, and oxygen vacancies [74].…”

This paper will provide a brief overview of the unique multiferroic material Bismuth ferrite (BFO). Considering that Bismuth ferrite is a unique material which possesses both ferroelectric and magnetic properties at room temperature, the uniqueness of Bismuth ferrite material will be discussed. Fundamental properties of the material including electrical and ferromagnetic properties also will be mentioned in this paper. Electrical properties include characterization of basic parameters considering the electrical resistivity and leakage current. Ferromagnetic properties involve the description of magnetic hysteresis characterization. Bismuth ferrite can be fabricated in a different form. The common forms will be mentioned and include powder, thin films and nanostructures. The most popular method of producing thin films based on BFO materials will be described and compared. Finally, the perspectives and potential applications of the material will be highlighted.

“…Although, due to search of new multifunctional materials, the recent work carried out is the very important and needed [12][13][14][15]. Rao et al reported the multifunctional properties of mullite-type structured Nd-doped Bi 2 Fe 4 O 9 and the spinorbital coupling by D-M interactions enhances the ferromagnetic (FM) behavior of the Nd-doping Bi 2 Fe 4 O 9 [12].…”

“…They proposed that the FM Bi 2 Fe 4 O 9 is a semiconductor with an indirect optical bandgap of 1.732 eV and the exchange mechanism started to work, resulting in the exchange splitting in Bi 2 Fe 4 O 9 , while the antiferromagnetic (AFM) Bi 2 Fe 4 O 9 is a multiband semiconductor without splitting of the majority and minority spin states [13]. In another study, the researchers believed that Zn substitution in Bi 2 Fe 4 O 9 would induce p-type conductivity, suggesting that 3d transition metal ions doping in Bi 2 Fe 4 O 9 provides the capabilities to develop low-bandgap, heterojunction-based optoelectronic devices [14]. In addition, Pooladi et al studied the Bi 2 Fe 4−x Mn x O 9 (0.0 ≤ x ≤ 1.0) nanoparticles synthesized by reverse chemical co-precipitation method.…”

This work reports the structure, electrical and magnetic properties of the orthorhombic (Pbam) structured bulk Bi2Fe4O9 synthesized by the solid-state reaction process. Bi2Fe4O9 has been studied using several experimental techniques such as X-ray diffraction, scanning electron microscopy, Raman spectroscopy, dielectric spectroscopy, and magnetometry. Rietveld-refined X-ray diffraction data and Raman spectroscopy results clearly reveal the formation of Bi2Fe4O9 perovskite structure and all the peaks of Bi2Fe4O9 perfectly indexed in the orthorhombic (Pbam) structure. It has been established that the Raman spectrum identified Ag, B2g, and B3g active optical phonon modes, and that the Raman peak at 470 cm−1 may have a magnetic origin. As a result, the coexistence of weak ferromagnetic and antiferromagnetic orders in Bi2Fe4O9 ceramic was established. The remanent magnetization (2Mr) and coercivity (2Hc) are 8.74 × 10−4 emu/g and 478.8 Oe, respectively. We report a remarkable multiferroic effects in polycrystalline Bi2Fe4O9 ceramic. These characteristics make this material very useful in technology and practical applications.

“…In addition, they also found that the Gddoped Bi 2 Fe 4 O 9 samples had much higher photocatalytic degradation of MB dye than the undoped Bi 2 Fe 4 O 9 [22]. From the point of theory, Ameer et al used the firstprinciple calculations to study the effect of 3d transition metal (TM) ions (Sc, Ti, V, Cr, Mn, Co, Ni, Cu, and Zn) on the structural, electronic, and magnetic properties of ferromagnetic Bi 2 Fe 4 O 9 and provided a comprehensive understanding of the possible effects of 3d TM dopants on Bi 2 Fe 4 O 9 [23].…”

In this paper, we report the synthesis, phase formation, and basic characterization of polycrystalline Bi2Fe4O9, Bi1.98Ba0.02Fe4O9, and Bi1.98Ce0.02Fe4O9 samples prepared by the sol-gel technique. The crystal structure of the prepared samples has been characterized by means of X-ray diffraction and Raman scattering spectroscopy. All the obtained XRD peaks can be indexed to the orthorhombic Pbam structure and reveal the formation of Bi2Fe4O9. The Raman spectrum identifies Ag, B2g, and B3g active optical phonon modes. The crystallite size and morphology of the nanoparticles have been analyzed using scanning electron microscope (SEM). Dielectric constant (ε′) decreases as the frequency increases, and it is constant at the higher frequency region which can be explained based on the ionic conduction phenomenon in the low frequency region. The ε′ values of Bi2Fe4O9(650–850), Bi2Fe4O9(800–850), Bi1.98Ba0.02Fe4O9, and Bi1.98Ce0.02Fe4O9 samples at 10 Hz frequency are about 37, 75, 90, and 393, respectively. The observed properties signify that these materials are very useful in advanced technological and practical applications.
