Figure 2
Derivation of the Fe₂Al₅ structure. (a) The CsCl-type structure of FeAl. (b) Deletion of half of the Fe atoms of FeAl such that the remaining ones form zigzag chains. (c) Opening the resulting Fe₂Al₄ framework creates channels ready for the inclusion of additional atoms. (d) The addition of δ Al atoms into the channels yields a structure with the composition Fe₂Al_4+δ.
