M'ossbauer study of the effect of Nb in Fe-based nanocrystalline alloy

摘要

Microstructure of nanocrystalline alloys of Fe73.5Cu1Nb3Si13.5B9and (Fe3Si)0.95Nb0.05 was investigated by M"ossbauerspectroscopy. A Nb-rich interfaciallayer with weak magnetism formed in the residual amorphous phase of these materials.It has an important effect on the exchange coupling and magnetic properties.
