Abstract

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.
