The magnetic properties of amorphous Fe–B–P–Nb–Cr alloys after their nanocrystallization are investigated. Due to optimizing the chemical composition and selecting heat-treatment conditions, in such alloys, the high values of saturation induction BS = 1.37 T and initial magnetic permeability μ10 = 7800 units as well as the low values of dynamical coercivity HC = 3 А/m are achieved at low core losses for magnetization reversal: P10/1000≅ 5 W/kg and P10/400≅ 1.5 W/kg.

Key words: soft-magnetic nanocrystalline alloys, Nb and Cr impurities, core loss, saturation magnetization, magnetic permeability.
