A polarized neutron investigation of the Fe3Si alloy

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

The magnetic moment of iron atoms in the ordered alloy Fe3Si has been investigated by polarized-neutron analysis. The magnetic moment of iron depends upon the relative population of the surrounding atoms like it has been already found in Fe3Al. However the moment of iron atoms with Si as nearest neighbours is lower than the moment of the corresponding iron atoms in Fe3Al. This result is related to the different number of 3p electrons in Si in respect to Al.

Riassunto

Mediante neutroni polarizzati è stato studiato il momento magnetico degli atomi di ferro nella lega ordinata Fe3Si. Il momento magnetico del ferro dipende dalla polazione relativa degli atomi circostanti come è stato già trovato per Fe3Al. Tuttavia il momento degli atomi di ferro che hanno Si fra i primi vicini è più basso che per i corrispondenti atomi di ferro nel Fe3Al. Questo risultato viene messo in relazione al diverso numero di elettroni 3p nel Si e nell’Al.
