• The structure and magnetic properties of Fe_<79.5>P_<12>C_6Cu_<0.5>Mo_<0.5>Si_<1.5> alloy is studied with ballistic galvanometer and by X-ray diffraction. Results show: after zero field annealing (ZFA) at 613K, nanocrystalline alloy having good soft magnetic properties of B_<800/Am>=1.4T, Hc=5.4A/m, μ_m=128000 is formed. The grain size of bcc-Fe precipitates is around 22nm. The lattice parameter a_0 of bcc-Fe is 0.28667nm, which is a little larger than that of pure iron. With the increase of annealing temperature, a_0 decreases. Annealing time t_a has little influence on a_0. The good soft magnetic property is explained by the reduction of effective anisotropy constant.
