Resumen:
Structural and magnetic properties of melt-spun Nd4.5Fe72Co3Cr2Al1B17.5 ribbons were studied by means of differential scanning calorimetry, Mössbauer effect spectroscopy, X-ray diffraction and FORC distributions. The presence of a solid solution - (Fe, Co) in ribbons annealed at 685ºC for 10 min was detected from ME spectra. Correlations between the observed structural changes at higher annealing temperatures, and modifications in the interaction fields of precipitated phases are discussed.
