Re: [sdpd] model based structure refinement



Hi,
I would say that if you know the space group, cell parameter and approximate atomic position, your structure is already solved. I suppose that what you want to do is to refine the crystal structure: for this you have to use some Rietveld refinement program, such as FullProf, GSAS... and input your initial parameters and have the program refine them.
Hope this helped

                  dear sir

if the sufficient knowledge about the structure is known(eg. lattice parameters, space group, approximate atomic positions etc), then what must be the stategy to solve similar structures.



i m working on soft ferrites which have spinel structureand space group Fd-3m.



i have made a lot of literature survey, but i cannot find the proper guidance about it



thanks in anticipation
