Isomer shift data in Fe-early transition metal and Fe-metalloid amorphous systems over wide composition range have been analyzed with the Miedema-van der Woude model of isomer shift in alloys. It is found that the model gives satisfactory description in some Fe-early transition metal systems, while in the others only the general trend is predicted. In the case of Fe-metalloid systems, a large deviation from the model is always observed at the Fe-poor side. This departure, which cannot be consistently accounted for by volume mismatch mechanism, is likely to be caused by hybridization effects.
