Abstract

Effect of high magnetic fields applied during annealing on the structure and magnetic properties were investigated for the melt-spun ribbons of Nd-Co-B system. When the annealing magnetic field is 100 kOe and the annealing temperature is lower than the Curie temperature TC of Nd 2 Co 14 B phase, the volume fraction of the Nd 2 Co 14 B phase and the coercivity values became much larger than those for the zero-field-annealed sample. A small but significant deviation from random alignment of Nd 2 Co 14 B grains was confirmed by the Rietveld analysis of the x-ray diffraction patterns for the sample field-annealed below TC.
