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 $B_{S}$ = 1.37 T and initial magnetic permeability $\mu_{10}$ = 7800 units as well as the low values of dynamical coercivity $H_{C}$ = 3 А/m are achieved at low core losses for magnetization reversal: $P_{10/1000} \cong$ 5 W/kg and $P_{10/400} \cong$ 1.5 W/kg.
Key words: soft-magnetic nanocrystalline alloys, Nb and Cr impurities, core loss, saturation magnetization, magnetic permeability.
