Dear Jae-Ho
The thermal parameters of the magnetic moments are identical to the
thermal parameters of the nuclei which they are attached to (along with
the x,y,z positions and occupancies). Normally they will refine much
better from the nuclear intensities which should extend to higher Q.

Dear Rietvelders,
I have a question, particularly to experts in magnetic structure
refinements. When does one need to refine anisotropic thermal factors
for the magnetic moments? We have a set of data, on which we work hard
to extract physically meaningful magnetic structures. The intensities
suggest that we need to use anisotropic thermal factors for the
magnetic moments, which the FullProf program allows. It is however
difficult to get a clear picture what it should mean physically. Any
comments will be appreciated.
Best regards,
Jae-Ho
