- Opis:
- In the present work multicomponent Co-based alloys with nominal composition $Co_{72-x}Fe_xZr_8B_{20}$ (x=10, 15, and 20 at. %) were synthesized by single-roller melt-spinning. The measurement of coercivity, $H_c$, reveals the soft magnetic behavior of investigated alloys. The value of $H_c$ 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, $_cT^{am}$, which increases from 300°C up to 462°C for alloy with x=10 at. % and x=2 0 at. %, respectively.
