摘要：

The magnetic properties of a series of Fe-P-C amorphous alloys were investigated. Fe80P13C7 shows the largest saturation magnetic flux density among all the Fe80P20-xCx (x=7-9) alloys, which is supported by the hyperfine field distribution. Synchrotron X-ray diffraction was performed to explore the underlying structure mechanism. It is found that Fe80P13C7 amorphous alloy has a larger atomic volume accompanied by a larger first peak position value of the reduced pair distribution function compared with those of Fe80P12C8 and Fe80P11C9. The origin of the unusual magnetic behavior of Fe80P13C7 is thought to be the large Fe-Fe bond length.
