摘要：
The aim of this work was to study the influence of iron substitution by Ce in amorphous and nanocrystalline Fe73.5xCexCu1Nb3Si13.5B9 (x = 3, 5, 7) alloys on their structure and magnetic properties. We present our structural study of amorphous alloys prepared by melt spinning method. Structures of samples were characterized by the X-ray powder diffraction (XRD). The structure stabilities and the structure evolution at a high temperature were addressed by the in-situ XRD experiment in DESY Hamburg. Experimental results confirm the influence of the Ce content on both magnetic and structural properties. Nanocrystalline state of the samples was confirmed by the presence of the ultra-fine Fe,Si phase. X-ray structure factor and the pair correlation function have been calculated for better characterization of as-quenched samples. Higher content of Ce worsens structural stability of nanocrystalline state and causes crystallization of CeFeSi phase. Magnetic properties reflect the observed structural changes.
