Dear Rietveld users,
I have some difficulty to refine a structure. A double-lattice
superstructure is suppose to superimpose on the orginal one, the lattice length
is slightly deviated. But when I tried to do this, the refinement is poor even
after I fix the fraction of the 2nd phase to be 5%. That may be because the
peaks for the 2 phases are almost at the same position and it seems gsas tries
to split the peak.....
Do anybody ever encounter this kind of problem? How did you solve it?
Thanks greatly!
Sincerely,
Ling Yang
