    摘要: Three nanocrystalline (nc-) Fe73.5Cu1Nb3Si13.5B9 (nc-FCNSB) samples were obtained from amorphous (a-) Fe73.5Cu1Nb3Si13.5B9 (a-FCNSB) samples by annealing for 30, 60, and 120 min at a temperature of 550°C. X-ray absorption near-edge-structure (XANES) spectra of these samples were measured at the Fe L3,2-edge using the sample drain current mode at room temperature. The intensities in the Fe L3,2-edge XANES spectra of nc-FCNSBs are significantly different from that of the Fe–Si–B alloy, indicating that Cu and Nb strongly influence the Fe 3d local electronic structure. Crystallization of the FCNSB alloy under the optimum annealing condition improves the magnetic properties of the nc-FCNSB alloys.
