MS-68: Symmetry aspects of magnetic order and magnetic properties
Invited: Laura Chaix (France), Fabio Orlandi (UK) | ||
Session Abstract | ||
The symmetry of commensurate and incommensurate magnetic structures can be unambiguously described using magnetic space and superspace groups. The description of symmetry of the magnetically ordered lattices and the involved order parameters are central concepts to fully characterize magnetic phases: symmetry provides a robust description of the spin- configuration modes and its constraints consistent with the parent paramagnetic phase and the magnetic propagation vector. Further, the assignment of a symmetry group for a magnetic phase conveys unequivocally other important properties coupled with the magnetic ordering. Symmetry-governed properties associated with magnetic transitions include ferroelectric polarization, ferromagnetic magnetization, various Hall-effect-type transport properties, and multiferroicity. For all abstracts of the session as prepared for Acta Crystallographica see PDF in Introduction, or individual abstracts below. The advances and challenges of the symmetry role in the study of magnetic structures and properties is the focus of attention of the microsymposium. | ||
