Description
In this work, tight binding linear muffin-tin orbital (TB-LMTO) electronic calculations are used in order to study the magnetism of FeAlSi alloys. The calculations have been performed in alloys around the stoichiometric composition of the D03 structure (Fe75Al25-x Si x ). The theoretical results show a good agreement with Moessbauer data obtained by Si/Al substitution in Fe75Al25-x Si x alloys. However, the calculations predict a very different behaviour for Fe11Al5-x Si x composition. They indicate that the magnetism of these intermetallic alloys around the stoichiometric D03 structure (Fe12Al4-x Si x ) is very dependent on their magnetic moment state (high or low) that depends on Fe content
