Mechanical milling has been widely used to synthesize new materials such as supersaturated solid solutions, amorphous and metastable phases, as well as to induce phase transitions and to alloy pure metallic elements. Materials obtained in this way present a high degree of structural disorder and nanometric crystallite sizes that significantly influence their physical properties. In this work we report on the characterization by Mössbauer spectroscopy, X-ray diffraction and AC susceptibility, zero field cooling-field cooling (ZFC-FC) and M vs H cycles measurements of  mechanically milled samples of composition (Fe79Mn21)1-xCux  (0.00 < x < 0.30).
