Theory of Magnetic Anisotropy in Nanostructured Alloy Cu70 Fe30

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.
