Abstract

To minimize the oxidation of Fe nanoparticles, 3 to 12 nm Fe nanoparticles have been synthesized by the modest‐temperature reduction of FeCl~2~ in a non‐polar solvent. Trioctylphosphine oxide and oleylamine were used to avoid additional oxidation introduced by surfactants in comparison with oleic acid. The magnetic properties of Fe nanoparticles with different sizes reveal that the saturation magnetization (M~s~) of larger than 8.0 nm Fe nanoparticles is over 180 emu/g at 300 K.
