【Abstract】 Crystallization of amorphous Ce₂Fe₂₃B₃ alloys as well as structure and mag-netic properties of metastable compound Ce₂Fe₂₃B₃ were studied. X-ray diffraction analysisconfirmed that the crystal structure of Ce₂Fe₂₃B₃ compound is body-centered cubic, its lat-tice constant α=1.417 nm. Measurement of room temperature hyperfine field ofCe₂Fe₂₃B₃ observeed that the size of Fe magnetic moment in different Fe site is orderlyμ_Fe（48e₁）>μ_Fe（48e₂）>μ_Fe（48e₃）>μ_Fe（16c）>μ_Fe（24d）. Average magnetic moments per Fe atomand per Ce atom are 1.94 and 0.85μ_B respectively.更多还原
