The (Nd,Ce,Pr)-Fe-(Si,Al) amorphous ribbons with thickness up to 100 mu m o
btained by the melt-spinning method exhibit hard magnetic properties in as-
cast state. The large glass-forming ability of all these alloys, as well as
the positive behavior of the hard magnetic properties, with increasing rib
bon thickness, allowed us to obtain bulk amorphous alloys with hard magneti
c properties. (C) 1999 Elsevier Science B.V. all rights reserved.
