I have grown a Bismuth ferrite sample through solid state and I observed that there are some secondary phases due to iron sillenite (Bi25FeO40). I am in need of Bi25FeO40 CIF file to refine the structure using rietveld analysis by GSAS +EXPGUI.
You can build one by yourself with the informations found here:

Thank you very much
The reference given by Timur is the best
Yes, the information at
is more than sufficient to start with.
