Eui-Suk:
The main problem in the Rietveld refinement of ferroelectrics
using laboratory x-ray data is the modeling of crystallite size
(if you have very small particle size) and microstrain.
In tetragonal ferroelectrics such as BaTiO3 and PbTiO3,
microstrain seems to correlate quite well with the

I am bothered by the number of requests in the Rietveld is mailing list
for copyright-protected data that I see crossing the ether. Particularly
since most of the requested data comes out of the ICSD database. The
ICSD database is available at a reasonable price to both industrial and
