摘要：

Sm(CobalFe0.1CuxZr0.03)(7) (x = 0.0-0.25) ribbons have been prepared by melt spinning. The effects of annealing parameters on coercivity and its temperature dependence have been Studied systematically. It is found that the melt-spinning technique remarkably improves the magnetic properties and simplifies the annealing process. The high-performance precipitation-hardened magnets can be obtained by only short-time ageing and slow cooling from 850 to 400 degrees C, without the standard solid solution. More interestingly, the temperature coefficient of coercivity of the ribbons can be tuned through adjustments of the processing parameters.
