Resumen:
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).
