Mechanically alloyed Sm-Co nanocrystalline powders were investigated. It was shown that a room-temperature coercivity of 41 kOe was obtained in Sm2Co7 powders. It was found that intrinsic coercivity of the powders increased with an increasing amount of Cu, and short annealing time produces 1:7 phase with higher crystalline anisotropy, resulting in larger coercivity.
