Abstract:
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 BiFeO 3 single‐phase NPs with the absence of any secondary bismuth oxide phases, a crucial issue for multiferroic features at room temperature.
