“…Figure 1 shows the X-ray diffraction (XRD) patterns of Bi 1−x Ba x FeO 3 (x = 0.0, 0.1, 0.2, 0.3) measured at room temperature. The XRD peaks show the typical rhombohedral type perovskite structure [16]. Apart from the main BiFeO 3 peaks, few minor peaks belonging to Bi 2 Fe 4 O 9 /Bi 24 Fe 2 O 39 /Bi 2 O 3 are also visible.…”

Bi 1−x Ba x FeO 3 (0 ≤ x ≤ 0.3) nanopowders were synthesized using sol-gel technique. The structural and magnetic properties were investigated using X-ray diffraction, SEM and VSM. As Ba 2+ doping concentration was increased, the structure of the samples changed from rhombohedral to tetragonal or monoclinic. The structural change might be an important factor for achieving the ferroelectric properties in this material. The lattice parameters were observed to increase with increase in Ba 2+ concentration. All the M-H loops showed the ferromagnetic behavior. Magnetization was observed to enhance with increase in Ba concentration. The enhancement in the magnetization due to Ba 2+ doping may be due to the replacement of Bi 3+ ions by Ba 2+ which might have resulted in the suppression of spiral spin structure.

“…From the point of view of magnetic ordering, BFO is an antiferromagnet below the Néel temperature T N = 643 K. By increasing the Fe 3+ ion amount, the FeOFe superexchange effect becomes stronger, indicating that Fe 3+ ions and low oxygen vacancies can play an active role in the BFO structure and can also affect the display of magnetic properties . In addition to that, it is known from the literature that leakage currents in BFO limit its applicability with the existence of secondary phases such as Bi 2 Fe 4 O 9 , Bi 25 FeO 40 , Bi 2 O 3 , Fe 2 O 3 , valence fluctuations of Fe ions and oxygen vacancies, reported as the major reasons for the leaky behavior . Accordingly, in this work, the amount of the secondary phases in BiFeO 3 is limited by changing the Bi/Fe molar ratio with a direct impact on the magnetic properties.…”

The explosive expansion of multiferroics literature in recent years demonstrates the fast‐growing interest in this field. Although bismuth ferrite is one of the most extensively investigated multiferroic compounds combining magnetoelectric, i.e., antiferromagnetic and ferroelectric features at room temperature, the challenge of producing single‐phase particles remains because the role of multiple synthetic parameters must be unraveled. Herein, the facile synthetic route of aqueous coprecipitation is selected as the first synthetic step, followed by a 700 °C annealing stage to synthesize bismuth ferrite nanoparticles (NPs). This article aims to clarify the influence of ingredients such as precursors: base solution, acid and the Bi/Fe molar ratio, and the role of synthetic parameters such as pH level and reaction temperature toward higher yields of purer crystalline phases. Both structural and magnetic features' performance outline the significance of both stages on forming BiFeO3 single‐phase NPs with the absence of any secondary bismuth oxide phases, a crucial issue for multiferroic features at room temperature.
