Fe@C) nanoparticles have been successfully synthesized using the laser pyrolysis method and variable nozzle geometries. At large nozzle diameters, XRD and SAED analysis clearly identified distinct α‐Fe and phases. TEM and HRTEM indicated that these Fe‐based nanoparticles have an average grain size of 3.5–10.2 nm. Temperature dependent Mössbauer spectra further confirm their distinct nanophases. By using a multi‐step reduction procedure, Fe@C powders can be disaggregated into stable, water soluble nanoparticles.
