    The structural and magnetic properties of iron nanoparticles formed in an aluminium matrix by combined helium and iron ions irradiation have been studied by small-angle X-ray scattering and susceptibility measurements. The formation of nanoparticles with average size of about 6.8 nm under iron ions irradiation has been found. The additional posterior irradiation with helium ions leads to the iron nanoparticles ordering with correlation length of 7.2(1) nm. The characteristic radius of iron nanoparticles and fractal dimension of the Al matrix were determined and magnetic properties of the Fe-Al nanomaterials were analysed.
