In the present work multicomponent Co-based alloys with nominal composition Co72-xFexZr8B20 (x = 10, 15, and 20 at.%) were synthesized by single-roller melt-spinning. The measurement of coercivity, Hc, reveals the soft magnetic behavior of investigated alloys. The value of Hc increases from 23 A/m for alloy with x = 10 at.% up to 32 A/m for alloy with x = 20 at.%. Further it was found that crystallization temperature of as-quenched alloys slightly varies with iron content and lays between 605 and 625°C. From the temperature dependence of magnetization it follows that partial substitution of cobalt by iron has positive influence on the Curie temperature of amorphous phase, T cam, which increases from 300°C up to 462°C for alloy with x = 10 at.% and x = 20 at.%, respectively.
