Description
We have obtained by high-energy ball milling of the powder elements, a nanostructured (Fe79Mn21)80Cu20 FCC with a grain size distribution of an average crystallite size of 8 nm. Moessbauer spectroscopy, AC-susceptibility and magnetization measurement results indicate that the FCC alloy displays two magnetic behaviors; a paramagnetic component that orders along over a wide temperature range below 220 K, and a minor antiferromagnetic fraction that is still ordered at room temperature. The average hyperfine field (Bhf=5.2 T) and the isomer shift (δ=0.07 mm/s) values at T=23 K show that Fe atoms are in a FCC structure that includes Mn and Cu atoms. In addition, we verified that presence of Cu stabilizes the FCC-Fe(Mn,Cu) phase
