We investigate the local magnetic characteristics of atomically disordered alloys stoichiometrically close to FePd2Au using Mössbauer spectroscopy at 77 and 300 K. With this information, we establish the distribution functions of the magnetic fields at the nuclei of the resonant iron atoms and their local magnetic moments. We demonstrate the presence of a dependence of the iron atom magnetic moments on the local atomic neighborhood and estimate parameters of its linear approximation.
