Hyperfine parameters evolution with the Cu content obtained by Mössbauer spectroscopy from mechanical milled (Fe79Mn21)1-xCux (x = 0.00 to 0.30) are presented. Results indicate that the Cu addition favors the formation of a FCC phase with two different magnetic states at room temperature. The trend of the hyperfine parameters with Cu composition suggests the incorporation of the Cu atoms at the regular FCC lattice sites.79Mn21)1-xCux (x = 0.00 to 0.30) are presented.
