It was found that Fe and Pt can be successfully alloyed in rod‐like nanostructures by electron‐beam‐induced deposition (EBID) using a Fe(CO) 5 precursor in an ultrahigh vacuum scanning electron microscope (SEM), followed by a 600 °C vacuum heating of the deposit and a subsequent surface platinum coating and a further 600–700 °C annealing treatment. By using high‐resolution transmission electron microscopy (HRTEM), image simulation and energy dispersion X‐ray spectra analysis, L1 2 ‐type intermetallic FePt 3 phase occurred in the nanostructure formed by the aforementioned EBID and postdeposition alloying processes.
