Abstract: Nd-(Fe, Co)-B alloys with Dy and Dy-AI additives have been studied by the Mössbauer effect and X- ray diffraction. The results indicate that the alloys consist of a tetragonal phase, a B-rich phase and a Nd-rich phase. The average magnetic moment of Fe atoms in the tetragonal phase has been determined. The variation of remanence due to Dy and Dy-Al additives has been derived from the Mössbauer data and found to agree with the results of magnetic measurements. The site substitutions of Dy and Al in the alloys are also discussed.
