Abstract
Amorphous Fe-2(B1-yZry) alloys, which are important as the residual amorpho us matrices in nanocrystalline Fe-Zr-B-Cu systems, were prepared by rapid q uenching from the melt for 0 less than or equal to y less than or equal to 0.55, The iron magnetic moment determined by Fe-57 Mossbauer spectroscopy a nd magnetic measurements shows an unexpected initial increase when Zr is su bstituted for B. This behaviour, together with the uncommon crystallization sequence, is attributed to the highly attractive B-Zr interaction.
