摘要： This work investigated the microstructure, magnetic properties, and crystallization kinetics of the as-spun and annealed alloy ribbons of (Fe$_{40-x}$Co$_{x}$Ni$_{40}$Si$_{6.33}$B$_{12.66}$Cu$_{1}$) $_{0.97}$Nb$_{0.03}$, where $x=0$, 6, 7, 8, 9, prepared using the melt-spinning method. The results show that adding a moderate amount of Co can improve the glass forming ability (GFA), the first peak crystallization temperature, and thermal stability of the as-spun alloy ribbons. With $x= 7$, the two-stage crystallization temperature interval $\Delta T_{x} = 90$ exhibits optimal thermal stability, and the alloy annealed at 673 K for 10 minutes shows the favorable combined magnetic properties, with $H_{\rm c} = 0.12$ A/m, $M_{\rm s} = 88.7$ A$\cdot$m$^2$/kg, and $\mu_{\rm e} = 13800$. The magnetic domain results show that annealing removes numerous pinning points in the magnetic domains of the alloy ribbons, making the domain walls smoother and effectively reducing the pinning effect.
