Abstract Nanocrystalline ternary Ce-Fe-B alloys with a composition close to a Ce 16 Fe 78 B 6 were prepared by melt spinning. The phase constitution and microstructure of the alloys were investigated by X-ray diffraction and Transmission Electron Microscopy. 57 Fe Mossbauer spectrometry was employed, allowing first to quantify the different phases, i.e. Ce 2 Fe 14 B and CeFe 2, and then to estimate the values of their respective hyperfine characteristics. By combining with the magnetic measurements, the magnetic moments of both Fe and Ce atoms in Ce 2 Fe 14 B phase were estimated based upon the Wigner-Seitz analysis of the RE 2 Fe l4 B structure. This work thus provides useful and relevant information for the investigation and applications of Ce-based hard magnets.
