Abstract

We report on Fe₄₂Co₄₂Nb₇B ₈Cu₁ nanocrystalline alloy with improved soft-magnetic properties, high Curie temperature and low high-frequency core loss. By annealing Fe₄₂Co₄₂Nb₇B₈Cu ₁ amorphous precursor at 873 K for 3.6 ks, α′-(Fe,Co) nanocrystalline phase with diameter of 5 nm precipitated from the amorphous matrix, yielding an Fe₄₂Co₄₂Nb₇B ₈Cu₁ nanocrystalline alloy. The resulting Fe ₄₂Co₄₂Nb₇B₈Cu₁ nanocrystalline alloy exhibits a high saturation magnetization of 1.87 T, low coercive force of 42 A/m, very high Curie temperature of 1240 K, as well as low core loss of 0.77 W/g at 10 kHz under a field of 1 T.
