Nanocrystalline Co₃₀Fe₇₀alloy synthesized by alkalide reduction

Synthesis and characterization of iron-cobalt (FeCo) alloy nanoparticles supported on carbon

“…materials and electrochemical devices including sensors, lithium-ion batteries, and supercapacitors [22,23,24]. FeCo nanoparticles supported on carbon microparticles have potential applications in catalysis for the synthesis ammonia, as magnetic materials in data storage devices, in the development of advanced microelectronics, and in biomedicine as contrasting agents for the detection of tumors using magnetic resonance imaging (MRI) and in photothermal-ablation therapeutics [25,26,27,28]. Notably, preformed FeCo alloy nanoparticles with magnetic properties embedded in a carbon matrix are suitable precursor materials for the synthesis of carbon-based FeCo nanohybrid systems [29].…”

Synthesis of high magnetization Fe and FeCo nanoparticles by high temperature chemical reduction

“…There is an ever increasing demand to achieve quality soft-phase nanoparticles because of their potential applications in magnetic storage [6], high performance inductors [7], biomedicine [8] and nanocomposite permanent magnets [9]. Many methods have been developed for their synthesis which includes chemical (polyol [1], reduction of Fe 2 þ and Co 2 þ ions using reductants [10,11], decomposition from carbonyls [4]) as well as mechanical [12], electrochemical [13], and chemical vapor deposition techniques [14]. However there is an overarching goal for developing a scalable process which enables the synthesis of small (5-10 nm), phase pure (absence of oxides and non-magnetic byproducts), monodisperse nanoparticles possessing high magnetic saturation values.…”

Stable Core Shell Co3Fe7–CoFe2O4 Nanoparticles Synthesized via Flame Spray Pyrolysis Approach

“…Compared to metallic magnetic nanoparticles and nanoalloy with enhanced magnetic properties, such as Fe, Co, FePt, and CoPt, − the soft magnetic FeCo alloy nanoparticles are of great interest for extensive applications because of their unique magnetic properties, , such as large permeability, high saturation magnetization, and Curie temperature. As we know, alloying iron with 30 atomic % cobalt , results in a higher room temperature saturation magnetization (δ s = 245 emu/g), which make FeCo alloy nanoparticles show a huge potential in practical applications.…”
