- Abstract
- Amorphous (FexCo1-x)(85)B5ZryNb10- y (x = 0.6, 0.7, 0.8, or 0.9 and y = 7 or 8 at.%) ribbons were fabricated by the melt-spinning technique, and their thermal and magnetic properties were investigated. The results showed that all alloys had a fully amorphous structure, and the substitution of Zr for Nb resulted in high thermal stability and high saturation flux density (B-s) with fairly low coercivity (H-c < 21 A/m). Moreover, by varying the Fe/Co ratio, the optimum ratio with the highest B-s and low H-c was determined. As the Fe/Co ratio changed from 6:4 to 9:1, H-c decreased from approximately 20 to 9 A/m, and B-s also decreased gradually. A saturation flux density of 1.33 T was achieved with a coercivity of 9 A/m after optimization.
