We have measured X-ray absorption near edge structure (XANES) of mechanically alloyed Y2Fe and YFe2 system as a function of milling time. An amorphous phase is obtained by mechanical alloying for 100 hours in the Y2Fe system and for 500 hours in the YFe2 system. In both systems the intensity of Fe 1s-4pπ transition grows up significantly with increasing the milling time and apprcaches to that of a melt spun amorphous Y67Fe33 alloy. On the other hand, the shape of 1s-4pσ transition becomes broad with the milling time.
