Abstract

X-ray diffraction, Mössbauer and magnetization measurements were used to study FexCu1−x alloys prepared by ball-milling. The X-ray data show the formation of a nanocrystalline Fe–Cu solid solution. The samples with x≥0.8 and x≤0.5 exhibit bcc or fcc phase, respectively. Both the bcc and fcc phases are principally ferromagnetic for x≥0.2, but the sample with x=0.1 remains paramagnetic down to 78 K. The influence of the local environment on the hyperfine parameters and the local magnetic moment are discussed using calculations based on the discrete-variational method in the local density approximation.
