The SIG 16 mission is to develop and strengthen links and interactions in the community of scientists studying condensed matter using magnetic crystallography.

The topics covered by the SIG are :

• Magnetic crystallography tools and their development/implementation
• General use of magnetic crystallography
  • magnetic compounds, including magnetic perovskites,  magnetic functional materials, molecular magnets, altermagnets
  • magnetic ordering,  magnetic phase transitions, complex magnetic structures (incommensurate and quasiperiodic)
  • co-representations, spin space groups and their applications, including altermagnetism
  • any field where symmetry is a key element to the understanding of properties
• Ad-hoc techniques, such as non-polarized and polarized neutron diffraction, or resonant X-ray diffraction.

Its main scopes and activities cover several aspects, such as :

• Contribution to the promotion of magnetic crystallography in the research community (development and usage of tools for magnetic symmetry determination)
• Promotion of the common magCIF standard (“good practice”)
• Promotion of a magnetic structure database built on the sharing of magCIF files
• Support for symposia and microsymposia on magnetic crystallography related topics in workshops and conferences
• Collaboration and joint actions with other SIGs to enlarge the impact of magnetic crystallography within the European community
• Sponsorship of schools and satellite meetings
• Elaboration of teaching materials, such as tutorials and lectures
• Promotion of pertinent publications in IUCr journals
