Intergrain interactions in nanocrystalline isotropic PrFeB-based magnets

In this paper, Pr/sub 9/Nd/sub 3.0/Dy/sub 1/Fe/sub 72/Co/sub 8/B/sub 6.9/Zr/sub 0.1/ alloy has been used to prepare a series of nanocomposites by intensive milling with various amounts of Fe. Exchange-coupling phenomena have been studied by analyzing the evolution of the corresponding /spl delta/J values when varying the i) Fe content, ii) annealing temperature, i.e. grain size, and iii) measurement temperature, i.e. variation of the exchange length.
