Talk will focus on the role of magnetic symmetry in the solution and refinement of magnetic structures. This will include discussions of magnetic neutron diffraction, the proper description of a magnetic structure (e.g. supercell, wave or irrep-mode parameters), magnetic space groups and superspace groups, magnetic systematic absences, the use of symmetry operators to constrain magnetic models, and the use of symmetry in widely-available structure solution/refinement packages.
