Resumen:
In the last decade, great emphasis has been placed on the nanosized materials to study the unique physical properties that derived from size reduction effects down to the nanodimension and from the surface to bulk ratio that for coarse ones[1]. Frustration of the exchange interactions, disorder and surface effects have been claimed to interpret structural and magnetic properties [2]. In this work, the effect of Cu addition on the structural, hyperfine and magnetic properties of metastable alloys FCC-(Fe79Mn21)1-xCux (x = 0.00 to 0.30)prepared by ball milling is studied. The Mössbauer spectroscopy and X-ray diffraction obtained results are discussed in the frame of the Cu distribution atoms in the lattice structure.
