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. Be

Thermal factor for magnetic phase?

2014-09-23 Thread Jae-Ho Chung
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 sugg
