Abstract

See full text

The present invention provides a samarium-cobalt magnet and a method for preparing the same. The method comprises mixing an alloy powder with a zirconium powder in an amount of 0.1-0.35 wt % of the weight of the alloy powder to form a mixture. The alloy powder is formed from 10.5-13.5 wt % of samarium, 12.5-15.5 wt % gadolinium, 50-55 wt % of cobalt, 13-17 wt % of iron, 4-10 wt % of copper, and 2-7 wt % of zirconium. The method brings about at low costs a samarium-cobalt magnet having a positive temperature coefficient of remanence.
