A mostly single bcc phase with grain sizes of 15-20 nm was prepared by crystallization of amorphous Fe-P-C-Mo-Cu-Si alloys.The Bs value (H=10000 Oe) reaches 1.595 T for Fe(79.5) P(12)C6Cu(0.5)Mo(0.5)Si(1.5) alloys. The low core loss of 0.14 w/kg at 1.3 T and 50 Hz was confirmed for the bcc Fe(79.5)P(12)C6Cu(0.5)Mo(0.5)Si(1.5) alloy.The structures of the alloy annealed at different temperatures have been investigated by means of Xray diffraction and transmission electron microscope. The relationship between the structure and magnetic properties of the alloy is discussed.
