Hello Anuruddha Mishra

For LSFCO, do you mean La0.6Sr0.4Fe0.8Co0.2O3? If so, this is a CIF file I found in an answer gave by Dr. Marcella Bini, in a past discussion:

It's difficult to obtain JCPDS cards because they are a paid database, but I can give you an alternative. You have now a CIF file, and it's possible to generate a hkl list, using this CIF file and the softwares VESTA or Mercury. With the hkl list, you have the same information as a JCPDS card would give you, as I described in another discussion:

I am attaching the hkl list for this structure, and a .xy file of the calculated patter. However, if you want to perform a Rietveld Refinement, you need the CIF file, not the JCPDS card. Please, send a reply if you need help with this step.

That's the rhombohedral structure. You will find some tetragonal structures if you use the (free) Crystallography Open database.
