Co3C magnetic nanoparticles have been synthesized using supercritical conditions of ethanol. The phase structure of the samples has shown two phases of orthorhombic Co3C and Co structures. The morphology of the prepared nanoparticles reveals a spherical-like shape. Tailoring the synthesis parameters has led to controlling the magnetic properties depending on the ratio of Co3C:Co in the samples. The magnetic properties of the samples have been measured, revealing ferromagnetic behavior. The data yield coercivity (HC) was of 600–950 Oe and saturation magnetization (MS) of 20–38 emu/g. The results present alternative approach to nucleate Co3C magnetic nanoparticles. The synthesis method will be optimized in the future to produce a pure Co3C phase structure.
