Influence of mechanical milling on the physical properties of SmCo5/Fe65Co35 type hard/soft magnetic nanocomposite

► Shock or/and friction milling effect on the SmCo5/Fe65Co35 nanocomposite is given. ► The composites microstructure is formed primarily during shock milling. ► The best exchange coupling is for 8 h shock milling and annealing for 2 h/550 °C.
