“…25 Gas sensing properties have also been investigated in BiFeO 3 nanoparticles. 26 In this paper, we report preparation of pure and Cr-doped BFO nanoparticles by a combustion method without using any solvent. The crystal structure and morphology is studied by means of x-ray diffraction (XRD) and transmission electron microscopy (TEM).…”

BiFe 1-x Cr x O 3 (x=0.0, 0.05 and 0.1) nanoparticles are prepared by the combustion method without using any solvent. All the synthesized nanoparticles are single phase in nature, nearly spherical in shape and crystallize in distorted perovskite structure (space group R3c) with an average crystallite size of the order of 40 nm. The room temperature magnetization observed in BiFeO 3 nanoparticles is larger than that in the bulk. Saturation magnetization and coercive field increase with increasing Cr-doping. Strong superexchange interaction between Fe 3+ and Cr 3+ atoms is likely to give rise to such increase in magnetization with Cr-doping. Mössbauer data of these nanoparticles show ordered magnetic state in which Fe atoms are in 3+ oxidation states.

“…Gao et al [18] also synthesized BFO nanoparticles, which promoted the degradation rate of methyl orange to a high level under visible-light irradiation. In addition, Yu et al [38] reported that perovskite-structured BiFeO 3 nanoparticles also exhibited excellent gas-sensing properties, which were potentially useful for high-quality gas sensors.…”

Low-dimensional BiFeO 3 nanostructures (e.g., nanocrystals, nanowires, nanotubes, and nanoislands) have received considerable attention due to their novel size-dependent properties and outstanding multiferroic properties at room temperature. In recent years, much progress has been made both in fabrications and (microstructural, electrical, and magnetic) in characterizations of BiFeO 3 low-dimensional nanostructures. An overview of the state of art in BiFeO 3 low-dimensional nanostructures is presented. First, we review the fabrications of high-quality BiFeO 3 low-dimensional nanostructures via a variety of techniques, and then the structural characterizations and physical properties of the BiFeO 3 low-dimensional nanostructures are summarized. Their potential applications in the next-generation magnetoelectric random access memories and photovoltaic devices are also discussed. Finally, we conclude this review by providing our perspectives to the future researches of BiFeO 3 low-dimensional nanostructures and some key problems are also outlined.

“…At the same time, studies on the finite size effect of BFO have been carried out by different authors and some interesting properties (e.g., shift of Neel temperature, gas sensing properties, etc.) have been reported [20][21][22][23][24]. In order to improve magnetic and electrical properties, partial substitution of Bi 3+ -ions for rare-earths at the Asite, transition metal ions like Co 2+ and Sc 3+ at B-site or co-substitution with Pr/Mn, Pr/Sc, Nd/Sc ions at A/B sites respectively has been carried out [25][26][27][28][29][30][31][32][33][34].…”
