“…These data demonstrate an agreement with strong pinning model of domain walls, proposed by Gaunt [8]. According to [6,7], the coercivity of the as-melt-spun Fe 14 Nd 86 and Fe 28 Nd 72 ribbons at lower temperatures is associated with a domain wall pinning on the Nd-rich nanocrystals embedded in an amorphous-like matrix phase which are observed in the ribbons microstructure. For the interpretation of the temperature dependence of coercivity, temperature dependences of magnetization in the range 5-300 K were made to reveal the possible magnetic transitions.…”

“…According to [9], the first two transitions correspond to antiferromagnetic ordering temperature of the dhcp Nd (the onset of ordering on cubic sites). This suggests that the ferromagnetic transition at 34 K is related to the metastable fcc allotrope of Nd or Nd-Fe solid solution (Nd-based nanocrystals) [6,7]. Hence, the possible reason for an upsurge in the magnetization at high fields at temperatures lower than 34 K is the presence of fcc Nd and Nd-based phases.…”
