Abstract: Different Mo contents have been added into traditional Finemet alloy to form Fe_73.5Cu₁Nb_3-xMo_xSi₁₃B_9.5(x=0～3) alloys. The change in DC and AC magnetic properties with Mo for Nb substitution was investigated. The results show that, with adding Mo, although the DC relative permeability decreases and the coercive force increases slightly, the saturation flux density B_S can be increased, and the core loss of the alloy can be decreased. The AC permeability of samples contained Mo is higher than that of alloy without Mo content. Fe_73.5Cu₁Nb₁Mo₂Si₁₃B_9.5 alloy has the highest saturation flux density B_S. Fe_73.5Cu₁Nb₂Mo₁Si₁₃B_9.5 alloy has the best frequency dependence on the AC permeability and core loss.
