摘要：
Amorphous Fe-Ni-B alloy particles have been prepared by chemical reduction of Fe2+ and Ni2+ in aqueous solution by NaBH4. It was found that within a limited range of NaBH4 concentrations and pH values of the metal salt solution the particles are amorphous. Outside this range the precipitates are partly crystalline. The magnetic hyperfine fields of the amorphous particles, estimated from Fe-57 Mossbauer spectroscopy, are similar to those of amorphous ribbons with the same compositions.
