Dear Rietveld List Members,

I am working as a postdoc on the synthesis of (magnetic) iron sulfide
minerals. I would like to determine the composition of iron sulfide
mixtures quantitatively. Therefore I would like to use the Rietveld
program. The mixtures that I want to quantify consist of greigite,
pyrrhotite, mackinawite, marcasite, pyrite.

Does anyone know whether there are reports on the use the Rietveld
program to determine compositions of mixtures of iron sulfides?
I could not find a reference for the atomic coordinates of greigite,
does anyone know where to find this information?

Thanking you for your time,
Sincerely,

Hilde Passier
