The magnetic and structural properties of SmCo5+30%Fe magnetic nanocomposites obtained through mechanical milling are investigated by DSC, TGA, XRD and magnetic measurements. It is shown that above 923 K (650 °C) the hard and soft magnetic phases react to form Sm2(Co-Fe)17 as the hard magnetic phase and Fe-Co as the soft magnetic phase which leads to a significant loss of anisotropy. The difference in magnetic behavior between the nanocomposites exposed to high temperatures (up to 1323 K, 1050 °C) and those annealed at 873 K (600 °C) was analyzed..
