The
intermetallic based on transition metal compounds present interesting magnetic
properties for the technological applications (permanent magnets, magnetic
recording,. . .).  

 Cu₇₀Fe₃₀
nanostructured with crystallite size vary from 10 a 12 nanometers ha been
developed  by a   mechanical milling method. The iron and
copper distribution was clear. The distribution showed a homogeneous
distribution of iron and copper in a Cu-Fe obtained after 36 h milling.The
structural properties have been performed with X-ray diffraction. With in-
creasing milling times, Fe  diffuse into
the Cu matrix, which accelerates the formation of the magnetic nanostructure
Cu- Fe  alloys. The magnetic behavior is
investigated using Vibrating Sample Magnetometer (VSM). The binary alloys
nanocrystals possess ferromagnetic character at room temperature.
