we are up to perform a refinement of a neutron diffraction pattern with 
magnetic reflections. Since the manual of FullProf is surely correct 
but a hard stuff to learn from as a complete beginner to magnetic phase 
refinement:
(1) Is there a paper / publication to describe the idea of the magnetic 
phase in more detail?
(2) People here do not use the concept of matrices for the magnetic 
moments and prefer to do calculations with a triclinic symmetry for the 
magnetic phase. This seems a bit the hard way - isn't it possible to 
apply at least a subgroup of the crystallographic phase?
Anyways - if there is any one to help us out there, please could you please
- point us to text sources to understand the concept ?
- send one/some example files over here ?
In case you feel this is the basic stuff, please use my mail address 
(Carsten.Schinzer@uni-tuebingen.de) and not the reply-to address (which 
is the mailing list). I don't want to bother anyone with boring basics.
Thank you very much.
Carsten
