摘要：

Anisotropic SmCo;/Co nanocomposite powders have been prepared by electroless Co deposition on commercial SmCo;powders with hydrazine as reducer. The Co particles are mainly in the range of 8–27 nm and form dense/continuous soft magnetic coatings on the surface of SmCo;powders. Exchange coupling happened between the coated Co soft magnetic particles and the SmCo;hard phase. As a result, SmCo;/Co nanocomposite powders with remanence of73.58 emu/g and energy product of 13.74 MGOe were obtained in the optimum condition, as compared with those of70.52 emu/g and 13.40 MGOe for uncoated SmCo;powders. The effects of Co adding amount on Co particle size, coating morphology, and magnetic properties of SmCo;/Co products were investigated.
