Abstract:

Ribbons with compositions of Sm(Co0.70-xFe0.20Cu0.10Zrx)7.5, x=0~0.06, have been prepared by melt-spinning technique, in order to examine the change of their magnetic properties and structures with Zr content. Under their optimum-aged conditions, the value of coercivity increases drasticaly with the increase of Zr content, x, when 0.02
