Respected Researchers,

Thank you verymuch for your suggestions, But iam unable to get the CIF file for  BiFeO3 in R3m phase (Both COD and ICDD). so i kindly request the researcher to provide the CIF file of BiFeO3 in R3m phase if possible

thanks in advance 

CIF file for BiFeO3 with  R 3 c is attached with this message

Thank you very much sir for your prompt respond, but how can i convert this BiFeO3 in R 3 m phase since the Xpert pro plus well matches with R 3 m phase for my sample??

Thanks in advance

Dear Mr. Rajesh,

why are you unable to get the CIF from the COD? What is the problem?

best

Respected Frank Hoffmann,

in COD,the CIF file of BIFeO3 exists in R3c phase alone and  R3m phase does not exists. so please help me to get CIF file of BIFEO3 in R3m phase

Raman, see the image below...

Ian's tutorial is superb - now also with images - you should be able to get the CIF...
