The magnetic alloys of Cu-Fe () were prepared by a mechanical alloying method and their structural and magnetic behaviors were examined by X-ray diffraction and Mossbauer spectra. The magnetization curves did not distinctly show the saturation at 70 kOe for the concentrated alloys of . The Mossbauer spectrum of at room temperature shows one Lorentzian line of the paramagnetic phase, whereas the Mossbauer spectrum of consists of sextet Lorentzian line at room temperature and a centered doublet line. The Mossbauer spectra of measured in the temperature ranges from 13 to 295 K, implies that to consists of two magnetic phases. One superimposed sextet corresponds to the ferromagnetic iron in Cu and the other one indicates the superparamagnetic iron rich phase.
