Abstract

Using 57Fe Mössbauer spectroscopy, X-ray diffraction and magnetization measurements, magnetic properties of melt-spun Nd4.5Fe77B18.5 ribbon have been investigated after the annealing treatments which make nanocrystalline composite from the as-prepared amorphous state. Specimen ribbon which shows coercivity and is suitable for a permanent magnet consists of the mixture of Fe3B and Nd2Fe14B. Relative fraction of these phases in the ribbon have been determined.
